IntEnz Enzyme Nomenclature
EC 4.99.1.12

Names

Accepted name:
pyridinium-3,5-bisthiocarboxylic acid mononucleotide nickel chelatase
Other names:
LarC
P2TMN nickel chelatase
Systematic name:
Ni(II)-pyridinium-3,5-bisthiocarboxylate mononucleotide nickel-lyase (pyridinium-3,5-bisthiocarboxylate-mononucleotide forming)

Reaction

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.
