MmarC5_0110

Gene
MmarC5_0110
Protein
L-cysteine desulfidase
Organism
Methanococcus maripaludis (strain C5 / ATCC BAA-1333)
Length
397 amino acids
Function
Catalyzes the cleavage of L-cysteine to form 2-aminoprop-2-enoate and sulfide. The former then spontaneously hydrolyzes to pyruvate and NH(3). May be responsible for the production of sulfide required for the biosynthesis of iron-sulfur centers in this archaea.
Similarity
Belongs to the L-cysteine desulfidase family.
Mass
