内容記述 | Six mutants of Escherichia coli K12 AB1157 were isolated, the catalase activity of which was about from 10% to 60% of the activity of the wild type. Four mutants showed nomal composition and contents of the cytochromes . Two mutants showed nomal cytochrome composition, although having slightly less amounts of cytochromes than those of wild type. Measurement of the pyridine hemochrome spectra with the mutant cells having the 10west catalase activity, 10% of the parent, showed that protoheme content of the mutant was about 70% of the parent/s level. These results suggest that the defects in catalase activity of mutants are not due to heme deficiency, but due to some defect in synthesis of catalase apoprotein, caused by mutation of a cat gene as described previouly. All of the catalase-less mutants isolated in this work were most probably caused by one point mutation, so that the two mutants with about 10% of the catalase activity of parent may by useful for the analysis of the catalase gene in Escherichia coli. |
