ABSTRACT Vitamin B-12 (Cobalamin) Our goal was to create a strain of E. Coli which could produce vitamin B-12 (cobalamin) to help people who have vitamin B-12 deficiency. Vitamin B-12 deficiency is especially common in vegetarians and vegans, because it is found almost exclusively in meats and dairy products. In order to achieve B-12 production in E. Coli, we extracted the DNA sequence coding for the cobW gene in Cupriavidus metallidurans using PCR, and inserted the gene into an Ampicillin resistant plasmid containing GFP for proof of concept. Although humans are fairly good at removing excess vitamin B-12 due to its solubility in water, having unrestrained B-12 production in the body still is an unnecessary risk. In order to control the production of B-12, we linked the promoter's activation to the presence of the amino acid homocysteine, which is an indicator of low B-12 levels. If successful, we will hopefully create a safe way to help those who suffer from vitamin B-12 deficiency to enjoy a better quality of life. BACKGROUND File:BME494 placeholder Write a description of the image here PROOF OF CONCEPT DESIGN New Natural Part: Why are you using this part? How did you find this part? What database/ resources did you use? What primers will you use to isolate it and turn it into a BioBrick? Key Pre-existing Part: If you didn't need to use a new natural part, describe one important pre-existing BioBrick from the parts registry.org that you will use. Why are you using it? Describe how well-documented the part is. Do you trust it?
