Despite the practically unlimited number of possible protein sequences, the number of basic shapes in which proteins fold seems not only to be finite, but also to be relatively small, with probably no more than 10,000 folds in existence. Moreover, the distribution of proteins among these folds...
An estimated 20% to 30% of the proteins in humans arepolymorphic(Describes a protein for which amino acid sequence variants are present in a population of organisms, but the variations do not destroy the protein’s function), having amino acid sequence variants in the human population. >>>Man...
The gene coding for urate oxidase, an enzyme that catalyzes the oxidation of uric acid to allantoin, is inactivated in humans. Consequently, urate oxidase is used as a protein drug to overcome severe disorders induced by uric acid accumulation. The structure of the active homotetrameric enzyme r...
The PR65/A subunit of protein phosphatase 2A serves as a scaffolding molecule to coordinate the assembly of the catalytic subunit and a variable regulatory B subunit, generating functionally diverse heterotrimers. Mutations of the β isoform of PR65 are associated with lung and colon tumors. The...
There are four levels of protein structure: Primary Structure: The primary structure of a protein is its amino acid sequence. This amino acid sequence is determined by the base sequence of the gene which codes for the protein. Secondary Structure: Secondary structures have α-helices and β-plea...

Primary Structure of Proteins. The linear sequence of amino acids constitutes a protein's primary structure. The sequence is written from the amino-terminal end (the first amino acid) to the carboxyl-terminal end (the same sequence in which the protein is synthesized). All properties of a pr...

1、蛋白质的分子组成、结构与功能Structure and Function of Protein什么是蛋白质?蛋白质(protein)是由许多氨基酸(amino acids)通过肽键(peptide bond)相连形成的高分子含氮化合物。蛋白质研究的历史1833年,Payen和Persoz分离出淀粉酶。1838年,荷兰科学家 G. J. Mulder引入“protein”(源自希腊字proteios,意为primary...
【答案】：quaternary structure of protein：蛋白质的四级结构是指多亚基蛋白质中各个亚基的空间排布、亚基间的相互作用与基接触部位的布局。quaternarystructureofprotein：蛋白质的四级结构,是指多亚基蛋白质中各个亚基的空间排布、亚基间的相互作用与基接触部位的布局。
