Tuberculosis) Sp act (U/mg) 0.889 Cloned extract/control 1 AroQMt (Rv0948c) Sp act (U/mg) 127.38 Cloned extract/control 143.28 *AroQMt (Rv1885c) Sp act (U/mg) 94.23 Cloned extract/control 105.9. CM specific activity in Escherichia coli cells expressing either the AroQMt or the *AroQMt protein is determined to be, repectively, 143- and 106-fold higher than the enzyme activity obtained for Escherichia coli cells carrying the pET-23a(+) expression vector 674346 5.4.99.5 additional information - additional information R90Cit 10E4-fold decrease in the catalytic activity of kcat.
