Protein

Proteins (/ˈproʊˌtiːnz/ or /ˈproʊti.ᵻnz/) are large biomolecules, or macromolecules, consisting of one or more long chains of amino acid residues. Proteins perform a vast array of functions within living organisms, including catalyzing metabolic reactions, DNA replication, responding to stimuli, and transporting molecules from one location to another. Proteins differ from one another primarily in their sequence of amino acids, which is dictated by the nucleotide sequence of their genes, and which usually results in protein folding into a specific three-dimensional structure that determines its activity.

A linear chain of amino acid residues is called a polypeptide. A protein contains at least one long polypeptide. Short polypeptides, containing less than 20-30 residues, are rarely considered to be proteins and are commonly called peptides, or sometimes oligopeptides. The individual amino acid residues are bonded together by peptide bonds and adjacent amino acid residues. The sequence of amino acid residues in a protein is defined by the sequence of a gene, which is encoded in the genetic code. In general, the genetic code specifies 20 standard amino acids; however, in certain organisms the genetic code can include selenocysteine and—in certain archaea—pyrrolysine. Shortly after or even during synthesis, the residues in a protein are often chemically modified by posttranslational modification, which alters the physical and chemical properties, folding, stability, activity, and ultimately, the function of the proteins. Sometimes proteins have non-peptide groups attached, which can be called prosthetic groups or cofactors. Proteins can also work together to achieve a particular function, and they often associate to form stable protein complexes.

    Protein (band)

    Protein was a punk, alternative, post-grunge, metal band formed in 1994 in San Francisco, California.

    Forming their first band after they were kicked out of a San Francisco-area high school, vocalist/guitarist Josh Zee (the son of a professional folksinger) and drummer Dan Thompson played for several years in various local bands before forming the grungy alternative pop band Protein in 1994. The duo played several shows before replacing their part-time bassist with Russ Violet and made a good showing at a San Francisco music-industry showcase in 1996. Signed to Sony's Work subsidiary, Protein released their debut album, Ever Since I Was a Kid, which was released in 1997. A second album, Songs About Cowgirls, was released in 1999.
