- True or false The disruption of the beta-lactamase gene causes resistance to the antibiotic pencillinRemaining V Ha Question 17 Triose phosphate isomerase catalyzes the conversion of Glyceraldehyde-3- phosphate to Dihydroxyacetone phosphate. Glyceraldehyde-3-P Dihydroxyacetone phosphate The Km of this enzyme for its substrate Glyceraldehyde-3-phosphate is 1.8 x 10 M. When [Glyceraldehyde-3-phosphate] = 30 uM the rate of the reaction (v) was 82.5 umol/mL/sec and the Vmax was 132 umol/mL/sec. Assuming 3 nanomoles/mL of enzyme was used ([Eotal = 3 nanomol/mL) the kcat for this enzyme is: Select an answer and submit.
