Comments

case <OC:Actinobacteria>
| Function | A cysteine desulfhydrase that generates hydrogen sulfide, H(2)S. The H(2)S produced by this enzyme modulates the balance between respiration and glycolysis, and contributes to redox homeostasis. Probably eliminates toxic levels of Cys (which can induce oxidative stress). |
else
| Function | A cysteine desulfhydrase that generates hydrogen sulfide, H(2)S. The H(2)S produced by this enzyme may modulate central metabolism. |
end case
| Catalytic activity | RHEA:24931: H2O + L-cysteine = H(+) + hydrogen sulfide + NH4(+) + pyruvate
EC 4.4.1.1 PhysiologicalDirection=left-to-right (RHEA:24932) |
case <FT:1>
| Cofactor | pyridoxal 5'-phosphate |
end case
| Similarity | Belongs to the cysteine synthase/cystathionine beta-synthase family. Cds1 subfamily. |
