BCH Enzymes Ch6

Additional chemical compenent, such as a inorganic ion or a complex organic or metalloorganic molec that may be required by an enzyme

complex organic or metalloorganic molec

Coenzyme or metal ion that's very tightly bound or covalently bound to the enzyme protein

A complete, catalytically active enzyme together w/its bound coenzyme and/or metal ions

protein portion of a holoenzyme

Energy derived from enzyme-substrate interaction

The ability of an enzyme to discriminate b/w a substrate and competing molec

When enzyme-substrate interactions replace most or all of the H bonds b/w the substrate and water

Concentration of substrate that leads to half-maximal velocity

Max # of enzymatic rxns catalyzed per sec

Type of enzymes which have increased or decreased catalytic activity in response to certain signals, thereby altering the rate of metabolic sequences.

Enzymes which function through reversible, noncovalent binding of regulatory compounds, which are generally small metabolites or cofactors

Regulatory compounds that are generally small metabolites or cofactors

Regulatory enzymes for which substrate and modulator are identical are called ___

When the modulator is a molecule other than the substrate, the enzyme is called ____

Enzymes which attach phosphoryl groups to specific aa residues of a protein

Enzymes which remove phosphoryl groups

Inactive precursor of a consensus sequence which is cleaved to form the active enzyme
