Amino Acid Sequence
Medical Definition: | The order of amino acids as they occur in a polypeptide chain. This is referred to as the primary structure of proteins. It is of fundamental importance in determining PROTEIN CONFORMATION. |
Guide Notes: | IM general; coord NIM with specific protein or peptide; when to index with MOLECULAR SEQUENCE DATA: see note there; DF: AMINO ACID SEQ or AA SEQ; use this heading when protein structure refers to the sequence of a protein; for covalent bonds to other mole |
Catalytic Domain - The region of an enzyme that interacts with its substrate to cause the enzymatic reaction. | |
Histone Code - The specific patterns of POST-TRANSLATIONAL PROTEIN MODIFICATION of HISTONES, i.e. histone ACETYLATION; METHYLATION; PHOSPHORYLATION; and ubiquitination, at specific amino acid residues, that are involved in assembly, maintenance, and modification of different chromatin structural states, such as EUCHROMATIN and HETEROCHROMATIN. | |
Repetitive Sequences, Amino Acid - A sequential pattern of amino acids occurring more than once in the same protein sequence. |
