Betaine reductase

Betaine reductase

In enzymology, a betaine reductase (EC number|1.21.4.4) is an enzyme that catalyzes the chemical reaction

:acetyl phosphate + trimethylamine + thioredoxin disulfide ightleftharpoons N,N,N-trimethylglycine + phosphate + thioredoxin

The 3 substrates of this enzyme are acetyl phosphate, trimethylamine, and thioredoxin disulfide, whereas its 3 products are N,N,N-trimethylglycine, phosphate, and thioredoxin.

This enzyme belongs to the family of oxidoreductases, 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 trimethylamine:thioredoxin disulfide oxidoreductase (N,N,N-trimethylglycine-forming).
