The human genome, categorized by function of each gene product, given both as number of genes and as percentage of all genes. [7] Proteins may also be classified based on their cellular function. A widely used classification is PANTHER (protein analysis through evolutionary relationships) classification system. [7]
The number in brackets, called a "sunid", is a SCOP unique integer identifier for each node in the SCOP hierarchy. The number in parentheses indicates how many elements are in each category. For example, there are 284 folds in the "All alpha proteins" class. Each member of the hierarchy is a link to the next level of the hierarchy.
Especially for enzymes the EC number system provides a functional classification scheme. [31] Similarly, gene ontology classifies both genes and proteins by their biological and biochemical function, and by their intracellular location. [32] Sequence similarity is used to classify proteins both in terms of evolutionary and functional similarity.
A part of F1 ATP synthase complex: alpha, beta and gamma subunits (The alpha and beta (or A and B) subunits are found in the F1, V1, and A1 complexes of F-, V- and A-ATPases, respectively, as well as flagellar (T3SS) ATPase and the termination factor Rho. The subunits make up a ring that contains the ATP-hydrolyzing (or producing) catalytic core.
In a number of iron–sulfur proteins, the [Fe 4 S 4] cluster can be reversibly converted by oxidation and loss of one iron ion to a [Fe 3 S 4] cluster. E.g., the inactive form of aconitase possesses an [Fe 3 S 4 ] and is activated by addition of Fe 2+ and reductant.
According to current understanding of the mechanism of the F 0 part, [2] the number of protons translocated per rotation is exactly equal to the number of subunits in the c ring. Recent structural studies show that this is not the same for all organisms. For vertebrate mitochondrial ATP synthase, the number of c subunits is 8 [3]. [4]
The quaternary structure of this protein complex would be described as a homo-trimer because it is composed of three identical smaller protein subunits (also designated as monomers or protomers). The number of subunits in an oligomeric complex is described using names that end in -mer (Greek for "part, subunit"). Formal and Greco-Latinate names ...
