[中文釋義] 蛋白質結構,三級
[英文釋義] The level of protein structure in which combinations of secondary protein structures (alpha helices,beta sheets,loop regions,and motifs) pack together to form folded shapes called domains. Disulfide bridges between cysteines in two different parts of the polypeptide chain along with other interactions between the chains play a role in the formation and stabilization of tertiary structure. Small proteins usually consist of only one domain but larger proteins may contain a number of domains connected by segments of polypeptide chain which lack regular secondary structure.
