Definition of asd-S-transferase

Curated sequence Q8TPT4: L-aspartate semialdehyde sulfurtransferase (EC 2.8.1.16). L-aspartate semialdehyde sulfurtransferase; EC 2.8.1.16. L-aspartate semialdehyde sulfurtransferase (EC 2.8.1.16)
Curated sequence 8500721: Homocysteine formation from aspartate semialdehyde (DUF39 component)
Curated sequence Q57564: L-aspartate semialdehyde sulfurtransferase (EC 2.8.1.16). L-aspartate semialdehyde sulfurtransferase; EC 2.8.1.16
Comment: In the reductive sulfuration of aspartate semialdehyde, the sulfurtransferase component is MA1821 or DvMF_1464 (see PMID:25315403 and PMC5764234) or Q57564 (from SwissProt). Although this reaction has not been biochemically demonstrated, a distant homolog performs a similar reaction, converting sulfoacetaldehyde to coenzyme M (see MJ1681 and PMID:30932481). (This family was formerly DUF39.)
