Web24 de jan. de 2013 · Overall kcat for lysozyme is about 0.5/sec, which is quite slow (Table 14.4) compared with that for other enzymes. On the other hand, the destruction of a bacterial cell wall may only require hydrolysis of a few polysaccharide chains. The high osmotic pressure of the cell ensures that cell rupture will follow rapidly. Turnover number has two different meanings: In enzymology, turnover number (also termed kcat) is defined as the maximum number of chemical conversions of substrate molecules per second that a single active site will execute for a given enzyme concentration $${\displaystyle [E_{T}]}$$ for … Ver mais AChE is a serine hydrolase with a reported catalytic constant > 10,000/s.
