4-Oxalocrotonatetautomerase from Pseudomonas putida mt-2 and 5-(carboxymethyl)-2-hydroxymuconate isomerase from Escherichia coli C catalyze the same reaction on substrates that differonly by a carboxymethyl group. While the structural resemblances between the substrates for these two proteins suggest that the enzymes might be evolutionarily related, the existing literature does not indicate an obvious
