[Conservative motifs in enzyme superfamily catalyzing formation of acyladenylates and compounds with carboxy group].
The search of conserved motifs was performed in enzymes catalyzing acyladenylate formation using ATP as AMP-donor. Besides a known motif, we have found a second conserved motif. Screening the SWISS-PROT database for occurrence of the motifs have showed that both motifs are highly characteristic and occur in all proteins of this superfamily. The motifs are separated by 200-250 residues in all sequences. It may suggest that the both motifs belong to the structural unit involved in acyl adenylate formation.
