E134Q | catalytic properties of the five different component enzyme activities of the alpha/Arg134Gln mutant complex show no significant changes as compared with those of the wild-type complex. In the alpha/Glu139Gln mutant complex DELTA3-cis-DELTA2-trans-enoyl-CoA isomerase shows 60% decreased turnover number and a significant increase in Km for 3-cis-tetradecenoyl-CoA | Escherichia coli |
E139Q | The replacement of Glu165 by Gln leads to a strongly reduced enzymatic activity. Tyr150 is not involved in isomerase catalysis | Escherichia coli |
