1.11.1.21 | malfunction | the null katG mutation has little effect on the growth rate in the absence of added H2O2. However, growth inhibition is evident with low levels of exogenous H2O2 | Caulobacter vibrioides |
1.11.1.21 | physiological function | the catalatic and/or peroxidatic activity of KatG is important in reducing H2O2 concentration to a steady-state level compatible with sustained exponential growth. Catalase-peroxidase clearly plays a critical role in stationary-phase survival | Caulobacter vibrioides |
