What is the optimum pH of peptidase?

Most arginases have an alkaline pH optimum, with maximal velocities observed in the range of pH 9.0-9.5. For the rat liver enzyme, plots of logVmax versus pH provide a pK value of ∼7.8-8.0, while pK values of 7.8 and 7.9 have been reported for the human liver and mouse liver enzymes.

What does the word statistic mean?

A statistic is a value calculated from a data sample. For example, the mean (average) is a statistic. You calculate the mean by adding up the values of the data you have and dividing by the number of values. Usually, you want to know the corresponding value for the whole population but this is impossible to obtain in practice. So you have to use a statistic calculated from a sample. For eaxmple, if you want to know the height of sixteen year old students in the UK, you cannot measure every single student. So you measure a sample (selected randomly), and calculate the average height of the sample. This is a statistic. See: http://www.stats.gla.ac.uk/steps/glossary/basic_definitions.html#stat
