Homology of 1-aminocyclopropane-1-carboxylate synthase, 8-amino-7-oxononanoate synthase, 2-amino-6-caprolactam racemase, 2,2-dialkylglycine decarboxylase, glutamate-1-semialdehyde 2,1-aminomutase and isopenicillin-N-epimerase with aminotransferases.

Profile analysis showed the title enzymes to be homologous with the aminotransferases. 1-Aminocyclopropane-1-carboxylate synthase is closely related to subgroup I of aminotransferases which includes aspartate, alanine, histidinol-phosphate, tyrosine and phenylalanine aminotransferase. 2,2-Dialkylglycine decarboxylase, glutamate-1-semialdehyde 2,1-aminomutase and 2-amino-6-caprolactam racemase are most similar to subgroup II which comprises aminotransferases with omega-amino acids as substrates. 8-Amino-7-oxononanoate synthase is closely related to both subgroup I and II, and isopenicillin-N-epimerase to subgroup IV with serine and phosphoserine aminotransferase. Aminotransferases and the title enzymes belong to a regio-specific family of evolutionarily related pyridoxal-5'-phosphate-dependent enzymes.
