2.5.1.65 | metabolism |
two biosynthetic routes to L-cysteine, each with its own specific cysteine synthase (CysK1 and CysM), are described in Mycobacterium tuberculosis, and a third putative sulfhydrylase in this pathogen, CysK2, is an S-sulfocysteine synthase, utilizing O-phosphoserine (OPS) and thiosulfate as substrates. Mycobacterial CysK2 thus provides a third metabolic route to cysteine, either directly using sulfide as donor or indirectly via S-sulfocysteine, cysteine synthasis pathways overview |

2.5.1.65 | physiological function |
the enzyme synthesizes S-sulfocysteine, the can also act as a signaling molecule triggering additional responses in redox defense in the pathogen upon exposure to reactive oxygen species during dormancy |
