Enzyme Structure and Classes
Enzymes can be
classified based Simple Enzymes,
on their structure Conjugated Enzymes
as
composed only of
protein (amino acid Simple Enzymes
chains)
composed of protein
Conjugated Enzymes
and nonprotein parts
protein component,
Apoenzyme
nonfunctional on its own
nonprotein component Cofactor
apoenzyme with
cofactor; functional Holoenzyme
conjugated enzyme
Essential ions,
Types of Cofactors
Coenzymes
mostly metal ions Essential ions
binds reversibly to the
enzyme and helps with Activator ions
substratebinding
