Amino acid sequence studies show that the aliphatic amidase (EC 220.127.116.11) from Pseudomonas aeruginosa PAC142 consists of a single polypeptide chain of 346 residues, giving an Mr of 38400. The evidence from the amino acid studies is in complete agreement with that deduced from the DNA sequence of the amiE gene. Studies of the protein from Pseudomonas putida A87 show that it differs from the Ps. aeruginosa protein by about 30 amino acid substitutions. It now becomes possible to relate changes in the enzyme which result in altered specificity to structural changes in the protein. © 1987.
