WebEach 'Active site' subsection refers to a single amino acid. There can be one or several 'Active site' subsections, depending on the nature of the catalytic mechanism. When the catalytic activity is brought about by bound metal ions or water molecules, or by direct contact between substrate and cofactor, we do not add any 'Active site' subsection.
