Abstract

Amino acid sequences of phosphoenolpyruvate carboxylases of Escherichiacoli (allosteric) and a cyanobacterium Anacystisnidulans (non-allosteric) were aligned. The pattern of homology suggests that the enzyme molecule is comprised of two distinct regions, namely, a conserved region (C-terminal half) and a variable region (N-terminal half). Among the amino acid residues which have previously been presumed essential for the catalytic activity, three histidine residues were found to be conserved, but cysteine residues were not. Furthermore, the conserved sequence unique to the enzyme was identified by comparison of the enzyme sequence with amino acid sequences in our data bank.
