Immunological and structural relatedness of catabolic ornithine carbamoyltransferases and the anabolic enzymes of enterobacteria.

Purified catabolic ornithine carbamoyltransferase of Pseudomonas putida and anabolic ornithine carbamoyltransferase (argF product) of Escherichia coli K-12 were used to prepare antisera. The two specific antisera gave heterologous cross-reactions of various intensities with bacterial catabolic ornithine carbamoyltransferases formed by Pseudomonas and representative organisms of other bacterial genera. The immunological cross-reactivity observed only between the catabolic ornithine carbamoyltransferases and the anabolic enzymes of enterobacteria suggests that these proteins share some structural similarities. Indeed, the amino acid composition of the anabolic ornithine carbamoyltransferase of E. coli K-12 ( argF and argI products) closely resembles the amino acid compositions of the catabolic enzymes of Pseudomonas putida, Aeromonas formicans, Streptococcus faecalis, and Bacillus licheniformis. Comparison of the N-terminal amino acid sequence of the E. coli anabolic ornithine carbamoyltransferase with that of the A. formicans and Pseudomonas putida catabolic enzymes shows, respectively, 45 and 28% identity between the compared positions; the A. formicans sequence reveals 53% identity with the Pseudomonas putida sequence. These results favor the conclusion that anabolic ornithine carbamoyltransferases of enterobacteria and catabolic ornithine carbamoyltransferases derive from a common ancestral gene.[1]
