Similarity:Both are made up of basic units of amino acids (bonded together bypeptide bohds);Contain the elements C,H, O, N;Differences:Polypeptides are shorter/ smaller/ less complex than proteins which are larger/ morecomplex;Polypeptides are straight chains of amino acids without a 3D folded...

The X-ray structure of human ABCG5/ABCG8 heterodimer in a nucleotide-free state, being the first atomic model of an ABC sterol transporter. Cholesterol is an essential component of vertebrate cell membranes. Animals maintain sterol balance by limiting di
This finding suggests that the manner in which a polypeptide backbone achieves a kinetically accessible local energy minimum might require that there is some local order or repeated structure throughout the aggregate. Thus, there seems to be a caveat about using the terms “ordered” versus “...
A novel polypeptide was isolated from mistletoe Viscum coloratum. The primarystructure of the polypeptide 'named viscotoxin B2' was determined to be KSCCKNTTGRNIYNT CRFAGGSRERCAKLSGCKIISASTCPSDYPK by Edman degradation. Viscotoxin B2 shared highsequence homology with viscotoxins isolated from Viscum...
Quaternary Structure: A quaternary structure is formed when two or more polypeptide chains associate to form a single protein. An example is haemoglobin which consists of fourpolypeptidechains. In some cases, someproteinscan have a non-polypeptide structure called a prosthetic group. These proteins ar...
The complete primary structure of the B subunit of calcineurin (protein phosphatase 2B) has been determined by automated sequence analysis. The protein consists of a single polypeptide chain of 168 residues, relative molecular mass 19200... A Aitken,CB Klee,P Cohen - 《European Journal of Bioche...
of about 1.1 MDa (Fig.1). Each PSII monomer comprises a PSII core complex, 6 ACPIIs, and a Chla-binding polypeptide, denoted as Psb-γ. Intriguingly, the ACPII antennae are exclusively monomers located along the shorter sides of the PSII core (Fig.1a–c), distinct from the trimeric ...
Eukaryotic mature mRNAs possess a poly adenylate tail (poly(A)), to which multiple molecules of poly(A)-binding protein C1 (PABPC1) bind. PABPC1 regulates translation and mRNA metabolism by binding to regulatory proteins. To understand functional mechani
Lamellar single crystals were formed from a random copolypeptide composed of 纬-benzyl l-glutamate and l-phenylalanine at the ratio of 4 to 1. The copolypeptide takes the 伪helical structure. The crystals were formed by casting dilute so... Y Tajima,M Anderson,PH Geil - 《International Journ...
