coenzymes bind loosely). While cosubstrates bind temporarily, prosthetic groups permanently bond with a protein. Prosthetic groups help proteins bind other molecules, act as structural elements, and act as charge carriers. An example of a prosthetic group is heme in hemoglobin, myoglobin,...
Prosthetic group:a cofactor or coenzyme that binds extremely tightly to theenzyme. Holoenzyme: an enzyme with its cofactors and/or coenzymes. Are cytochromes proteins? Cytochrome c Cytochromes areproteinsthat contain heme as their prosthetic group and whose principal biological function, in the cells ...
Tightly bound cofactors are referred to as prosthetic groups, an example being heme. One group of cofactors have adenosine monophosphate (AMP) included in their structure (eg, adenosine triphosphate, coenzyme A, FMN, FAD, nicotinamide adenine dinucleotide), while others are also small organic ...
Definition Cofactor is a nonprotein (organic or inorganic) factor necessary for the activity of an enzyme . This factor can be firmly bound to the enzyme (i.e., prosthetic group, e.g., cytochromes ) or freely dissociable (i.e., coenzyme , e.g., NAD(P)H). See Also Coenzyme ...
It may be a metal ion, loosely associated organic molecule (coenzyme, e.g., nicotinamide cofactor NAD(P)H), or a closely associated molecule (prosthetic group, e.g., heme). Cofactor recycling A system for recycling an expensive (usually nicotinamide) cofactor using a sacrificial substrate and...

Covering: 1996 to 2007 Cells require metal ions as cofactors for the assembly of metalloproteins. Principally one has to distinguish between metal ions that are directly incorporated into their cognate sites on proteins and those metal ions that have to become part of prosthetic groups, cofactors ...
