	Protein subunit - Wikipedia, the free encyclopedia
		In structural biology, a protein subunit or subunit protein is a single protein molecule that assembles (or "coassembles") with other protein molecules to form a multimeric or oligomeric protein.
		In some protein assemblies, one subunit may be referred to as a "regulatory subunit" and another as a "catalytic subunit." An enzyme composed of both regulatory and catalytic subunits when assembled is often referred to as a holoenzyme.
		A subunit is often named with a greek or roman letter, and the numbers of this type of subunit in a protein is indicated by a subscript.

		The constant regulatory subunit A serves as a scaffolding molecule to coordinate the assembly of the catalytic subunit and a variable regulatory B subunit.
		pp2a consists of a common heterodimeric core enzyme, composed of a 36 kda catalytic subunit (subunit c) and a 65 kda constant regulatory subunit (pr65 or subunit a), that associates with a variety of regulatory subunits.
		The PR65 subunit of protein phosphatase 2A serves as a scaffolding molecule to coordinate the assembly of the catalytic subunit and a variable regulatory B subunit.
