carbazole degradation-PWY-6550

SYSTEMATIC NAMEIUBMB Comments
(2E,4E)-6-(2-aminophenyl)-2-hydroxy-6-oxohexa-2,4-dienoate acylhydrolaseThis enzyme catalyses the third step in the aerobic degradation pathway of carbazole. The effect of the presence of an amino group or hydroxyl group at the 2-position of the substrate is small. The enzyme has no cofactor requirement [2].

to 1.86 A resolution, space group I422. The subunit of ht-CarCJ3 is divided into two domains, i.e., the core domain with residues 15-144 and 209-282, and the lid domain with residues 145-208. The invisible 10 amino acid residues Ile146-Asn155 correspond to the helix alpha4, which is the putative first alpha-helix in the lid domain. Sidechains of the active-site residues, Ser114 and His261, are clearly shown in the electron density mapJanthinobacterium sp. J3Q84II3707350
