Web15 sep. 2024 · A catalyst is a chemical that speeds up chemical reactions. In organisms, catalysts are called enzymes. Essentially, enzymes are biological catalysts. Like other catalysts, enzymes are not reactants in the reactions they control. They help the reactants interact but are not used up in the reactions. What is biocatalyst example? Web9 mei 2016 · The enzymatic properties of the wild-type and mutant enzymes were investigated in detail and the results are summarized in Table 4. The mutation of several predicted catalytic residues, including Asp39, Asp164 and Glu216 to alanine led to a complete loss of catalytic activity. doheny terrace
