O-acetyl-L-serine:L-homocysteine 2-amino-2-carboxyethyltransferase

O-acetyl-L-serine + L-homocysteine = L-cystathionine + acetate [RN:R10305]

R10305
Reaction

O-acetyl-L-serine [CPD:C00979];
L-homocysteine [CPD:C00155]

A pyridoxal 5'-phosphate protein. The enzyme, purified from the bacterium Bacillus subtilis, also has a low activity with L-serine (cf. EC 4.2.1.22, cystathionine beta-synthase).
