Accepted name: glyceraldehyde-3-phosphate dehydrogenase (arsenate-transferring)
Reaction: D-glyceraldehyde 3-phosphate + arsenate + NAD+ = 1-arsono-3-phospho-D-glycerate + NADH + H+
Glossary: 1-arsono-3-phosphoglycerate = [(2R)-2-hydroxy-3-phosphopropanoyl]oxyarsonate
Systematic name: D-glyceraldehyde-3-phosphate:NAD+ oxidoreductase (arsenate-transferring)
Comments: The enzyme, discovered in bacteria, is very similar to EC, glyceraldehyde-3-phosphate dehydrogenase (phosphorylating). However, the gene encoding it is located in arsenic resistance islands in the chromosome, next to a gene (arsJ) that encodes a transporter that removes the product, 1-arsono-3-phosphoglycerate, from the cell. Together the two proteins form an arsenic detoxification system.
