The 3 substrates of this enzyme are acetyl phosphate, methylamine, and thioredoxin disulfide, whereas its 3 products are N-methylglycine, phosphate, and thioredoxin.
This enzyme belongs to the family of oxydoreductases, specifically those acting on X-H and Y-H to form an X-Y bond with a disulfide as acceptor. The systematic name of this enzyme class is acetyl-phosphate methilamine:thioredoxin disulfide oxydoreductase (M-methylglycine-forming).
