Scientists at the University of Kent have trained an unfriendly bacterium to produce all of the components involved in anaerobic B12 production, filling in any missing molecular pieces that remain to reveal exactly how this remarkable vitamin is created.

This research discovery is significant as it could help people who suffer from vitamin B12 deficiency overcome any dietary restrictions they face in meeting their requirements for vitamin B12.

Vitamin B12

Vitamin B12 is a water-soluble vitamin that plays an integral part in helping your body make DNA, nourish the nervous system and form healthy red blood cells. You’ll find it naturally present in certain foods or added as supplements; cobalamin (the mineral cobalt contained within vitamin B12) is also available as a dietary supplement and prescription medication [1.]. Once eaten, vitamin B12 enters your system where it converts to its biologically active forms like methylcobalamin and 5-deoxyadenosylcobalamin [2.].

At an advanced age, your natural ability to absorb vitamin B12 decreases. Therefore, it becomes even more critical that you get sufficient amounts in your diet or through supplements as the years progress. Not getting enough can result in deficiency that affects many parts of the body including nervous system, digestive tract and blood cells; anemia being its signature symptom; others include appetite loss; involuntary tongue movement called glossitis; low red blood cell counts, white blood cell counts and platelets counts; low levels of protein in stomach linings; weight loss; breath that sounds shaky or hoarse; depression as well as changes to memory and concentration capabilities.

Vitamin B12 deficiency may be difficult to diagnose. Your body stores up to 2,000 times as much vitamin B12 as you consume each day, so signs and symptoms of deficiency may take years to appear. Megaloblastic anemia – which features abnormally large, abnormally nucleated red blood cells; memory problems; confusion; poor balance and coordination; as well as numbness or tingling sensations in hands or feet may result from this deficiency if left untreated.

Some observational studies have linked higher intakes or blood levels of vitamin B12 with decreased cancer risks; however, results from controlled trials remain mixed. Some research suggests that increased intake may reduce age-related macular degeneration risk; however more research needs to be conducted in this area. Vitamin B12 can be found readily available in animal products, fortified foods and dietary supplements; with oral forms including tablets or lozenges as well as sublingual preparations designed to dissolve under your tongue being available as oral dietary supplements; it’s also administered as prescription medication via injection – often for pernicious anemia or other conditions where vitamin B12 malabsorption or deficiency occurs.

Vitamin B6

Vitamin B6 is a water-soluble vitamin with several different names: pyridoxal 5-‘-phosphate (PLP), pyridoxine (5′-PNH), and pyridoxamine (5’-NHR). It plays a critical role in many bodily processes: DNA/RNA replication and production; amino acids production and nerve cell activity formation. Furthermore, B6 plays an integral part in iron absorption and metabolic processes.

Studies suggest that low levels of vitamin B6 may contribute to memory decline among older adults, particularly among those 65 or over. Low vitamin B6 levels increase your risk for Alzheimer’s disease and other forms of dementia; one research paper in Neurology tracked 271 adults age 65 or over for seven years and discovered those with higher plasma PLP had better memory test scores.

Studies show that Vitamin B6 helps relieve anxiety and depression by decreasing stress hormones, according to one small study. Furthermore, B6 plays an essential role in producing neurotransmitters such as serotonin and dopamine; additionally it may help ease PMS symptoms according to some research.

Researchers have recently made progress in understanding how our bodies utilize vitamin B12. Their investigation led them to trace B12’s journey from garden cress, which can absorb it from soil and store it away until later use. Their discovery could pave the way for B12-enriched plants that may overcome diet restrictions in countries like India where low levels of B12 deficiency exist.

As is well-documented, two pathways exist in nature for the de novo biosynthesis of vitamin B12. One requires oxygen while its anaerobic counterpart remains poorly understood due to difficulties obtaining purified enzymes from microorganisms. An international team of scientists have recently used Bacillus megaterium bacteria as part of an anaerobic B12 pathway research effort and acquired all the missing molecular pieces necessary for its synthesis – this information published by PNAS has given researchers greater understanding of this remarkable molecule’s creation process.

Now, the eight complementation groups identified in patients provide the framework for understanding intracellular processing of vitamin B12. Cobalamin, usually taken in transcobalamin form (TC), enters lysosomes where it is digested to release cobalmin to reach the cytosol where R group containing proteins such as CblC break it down further to release both vitamins and water molecules which then diffuse through lysosomal membrane receptors via interaction with LMBDM1 protein or other means (for instance via lipocalin family receptors).

Cobalmin binds to both LMBD1’s cytosolic face and MMACHC’s mitochondrial membrane surface for transport into mitochondria and subsequent energy production through oxidative phosphorylation.

Vitamin B9

Vitamin B9, commonly referred to as folate or folic acid, is essential for cell development. It helps the body use protein, produce red blood cells and make DNA. Folate can be found primarily in leafy vegetables. Unfortunately, your body cannot produce its own supply; so adequate levels must be consumed through diet alone in order to prevent birth defects such as spina bifida from developing.

Lack of vitamin B12 can lead to anemia, heart failure and neurological system issues. According to Cureus research published in 2020, deficiency could result in confusion, dementia and sensations of tingling/numbness due to inadequate myelination (an insulating layer that forms around nerves).

B12 is a water-soluble vitamin produced naturally by bacteria in both animals and humans’ stomachs and intestines, and then absorbed into their bloodstream to be used by cells for making red blood cells, producing amino acids and DNA, transporting oxygen through their bodies and carrying oxygen out to cells throughout.

Discovering that plants can absorb vitamin B12 is a major step forward in combatting global malnutrition. In the past, this nutrient was only readily available from animal sources and was difficult to obtain in plant-based diets; but with increasing numbers of people adopting vegetarian or vegan lifestyles for health and environmental reasons, we must now find ways to provide these populations with food packed with essential nutrition.

Researchers led by Professor Martin Warren, Chief Scientific Officer of Quadram Institute, were able to confirm that garden cress seedlings can successfully absorb and transport cobalamin into their vacuoles (parts of cells that store nutrients). They tracked this process using fluorescent B12 that emits green light when exposed to laser.

Researchers used computational tools to examine the structures of proteins involved in the absorption and processing of vitamin B12 within cells. This enabled them to pinpoint which parts of proteins contained chemical molecules that trapped it and determine how it could be released again.

The team also conducted extensive analysis of human genetic code to pinpoint which genes are involved in vitamin B12 production. CblC, CblF and CblH were identified as likely culprits responsible for intracellular B12 processing disorders; other genes may exist but were overlooked due to either not tolerating mutations (and thus being lethal embryonically), or because their function overlaps with another gene or can bypass any defects due to redundancies between their functions (allowing bypass of defect). No other disease-causing genes have yet been identified to date.
