2-hydroxychromene-2-carboxylate isomerase M-CSA #983 | Catalyzes the reversible glutathione-dependent isomerization of 2-hydroxychromene-2-carboxylate (HCCA) to trans-O-hydroxybenzylidenepyruvate (THBPA). HCCA isomerases are present in most aerobic organisms including microorganisms, plants, and animals. The group kappa GSH transferases (k-GSTs) are a close relative of the largest group of proteins in nature; the GST group. k-GSTs are dimers with a main catalytic domain, which is the N-terminal domain containing the thioredoxin domain, and the C-terminal domain which is mostly alfa-helical and unlike its GST relatives, inserted into the N-terminal domain. HCCA is a part of the naphthalene catabolic pathway of Pseudomonas putida. | Defined by 5 residues: SER:A-11VAL:A-168TRP:A-179ASN:A-181ASP:A-182 | EC: 2.5.1.18 (PDB Primary Data) |
