Many ion channel proteins are specialized to select for only a particular ion; for example, potassium and sodium channels often discriminate for only one of the two ions.: 232–34 Structural proteins Visa mer Proteins are large biomolecules and macromolecules that comprise one or more long chains of amino acid residues. Proteins perform a vast array of functions within organisms, including catalysing metabolic reactions Visa mer The number of proteins encoded in a genome roughly corresponds to the number of genes (although there may be a significant number of genes that encode RNA of protein, e.g. ribosomal RNAs). Viruses typically encode a few to a few hundred proteins, Visa mer Biosynthesis Proteins are assembled from amino acids using information encoded in genes. Each protein has its own unique amino acid sequence that is … Visa mer Proteins are the chief actors within the cell, said to be carrying out the duties specified by the information encoded in genes.
