EC 4.99.1.12     
Accepted name: pyridinium-3,5-bisthiocarboxylic acid mononucleotide nickel chelatase
Reaction: Ni(II)-pyridinium-3,5-bisthiocarboxylate mononucleotide = pyridinium-3,5-bisthiocarboxylate mononucleotide + Ni2+
Other name(s): LarC; P2TMN nickel chelatase
Systematic name: Ni(II)-pyridinium-3,5-bisthiocarboxylate mononucleotide nickel-lyase (pyridinium-3,5-bisthiocarboxylate-mononucleotide-forming)
Comments: This enzyme, found in Lactobacillus plantarum, is involved in the biosynthesis of a nickel-pincer cofactor. It catalyses the insertion of Ni2+ into the cofactor forming a covalent bond between a carbon atom and the nickel atom.
