EC 184.108.40.206 - Lactate racemase
IntEnz Enzyme Nomenclature
lactic acid racemase
larA (gene name)
The enzyme has been characterized from the bacterium Lactobacillus plantarum and appears to be restricted to lactic acid bacteria. It contains a unique nickel-containing cofactor, pyridinium-3-thioamide-5-thiocarboxylate mononucleotide Ni pincer complex.
