EC 2.8.5.1 Details

show Brenda entry

EC number

2.8.5.1

Accepted name

S-sulfo-L-cysteine synthase (3-phospho-L-serine-dependent)

Reaction

O-phospho-L-serine + thiosulfate = S-sulfo-L-cysteine + phosphate

Other name(s)

cysK2 (gene name)

Systematic name

thiosulfate:3-phospho-L-serine thiosulfotransferase

Comment

The enzyme, which has been characterized from the bacterium Mycobacterium tuberculosis, has no activity with O-acetyl-L-serine. Requires pyridoxal 5′-phosphate. cf. EC 2.5.1.144, S-sulfo-L-cysteine synthase (O-acetyl-L-serine-dependent).
