title: Similar structures in gamma-carboxymuconolactone decarboxylase and beta-ketoadipate succinyl coenzyme A transferase.
abstract: gamma-Carboxymuconolactone decarboxylase (EC 4.1.1.44) and beta-ketoadipate succinyl coenzyme A transferase (EC 2.8.3.6) mediate different steps in the beta-ketoadipate pathway. Antisera prepared against the Pseudomonas putida transferase cross-reacted immunologically with the decarboxylase from the same organism. The transferase is formed by association of two nonidentical protein subunits. The NH2-terminal amino acid sequences of the two nonidentical transferase subunits resembled each other and also were similar to the NH2-terminal amino acid sequence of the decarboxylase.
