What is a domain containing protein?
A protein domain is a region of the protein’s polypeptide chain that is self-stabilizing and that folds independently from the rest. Each domain forms a compact folded three-dimensional structure. Many proteins consist of several domains. One domain may appear in a variety of different proteins.
What does LIM domain stand for?
LIM domains are protein structural domains, composed of two contiguous zinc fingers, separated by a two-amino acid residue hydrophobic linker. The domain name is an acronym of the three genes in which it was first identified (LIN-11, Isl-1 and MEC-3).
What is globular domain?
Larger globular proteins are usually made up of two or more recognizable and distinct structures, termed domains or modules. These are compact, folded protein structures that are usually stable by themselves in aqueous solution. Typical domain structures consist of hydrophobic cores with hydrophilic surfaces.
What does LIM protein stand for?
LIM proteins carry two tandem copies of the LIM domain (the acronym stands for Lin-11, Islet-1, and Mec-3 —the three original members of the family), a unique cysteine-rich zinc-binding domain (two zinc fingers per LIM domain, for a total of four zinc fingers) involved in protein-protein interactions.
Which is globular protein?
Globular proteins or spheroproteins are spherical (“globe-like”) proteins and are one of the common protein types (the others being fibrous, disordered and membrane proteins). Globular proteins are somewhat water-soluble (forming colloids in water), unlike the fibrous or membrane proteins.
Which is a globular protein?
Among the most known globular proteins is hemoglobin, a member of the globin protein family. Other globular proteins are the alpha, beta and gamma (IgA, IgD, IgE, IgG and IgM) globulin.
Are all enzymes globular proteins?
Most enzymes are globular. The primary way globular proteins maintain their tertiary structure is called the Hydrophobic Effect.
