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.
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]
In molecular biology, protein fold classes are broad categories of protein tertiary structure topology. They describe groups of proteins that share similar amino acid and secondary structure proportions. Each class contains multiple, independent protein superfamilies (i.e. are not necessarily evolutionarily related to one another). [1] [2] [3]
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.
A protein superfamily is the largest grouping of proteins for which common ancestry can be inferred (see homology). Usually this common ancestry is inferred from structural alignment [ 1 ] and mechanistic similarity, even if no sequence similarity is evident. [ 2 ]
[4] Usually, proteins are dissolved in plasma and globulin is one of them. The protein serum consists of the serum protein which is about 6 to 8 g/dl then albumin makes 3.5 to 5.0 g/dl then the rest should be the globulins. The section where globulins fractions are located is made up of proteins, enzymes, and immunoglobulins.
[3] [4] The sequence of a protein is unique to that protein, and defines the structure and function of the protein. The sequence of a protein can be determined by methods such as Edman degradation or tandem mass spectrometry.
