  • Hydrogen
  • During protein synthesis the amino group of the amino acid being added is coupled to the carboxyl group of the prior amino acid, and two hydrogen atoms and one oxygen atom are removed as a water molecule (H 2 O) and the peptide bond is formed (see Figure 2). (encyclopedia.com)
  • Glycine takes on a special position, as it has the smallest side chain, only one Hydrogen atom, and therefore can increase the local flexibility in the protein structure. (wikipedia.org)
  • His most notable scientific contributions were the development of sundry physical techniques to study protein structure and function (especially hydrogen-deuterium exchange), and his definitions of protein primary, secondary, tertiary and quaternary structure. (wikipedia.org)
  • Concentration
  • The morpheein model highlights the importance of conformational flexibility for protein functionality and offers a potential explanation for proteins showing non-Michaelis-Menten kinetics, hysteresis, and/or protein concentration dependent specific activity. (wikipedia.org)
  • regulation
  • Although assembly of the mitotic spindle is known to be a precisely controlled process, regulation of the key motor proteins involved remains poorly understood. (nih.gov)
  • Helix
  • These restricted movements, when repeated through several amino acids in a chain, yield the two main types of protein secondary structure: the alpha ( α ) helix and the beta ( β ) strand. (encyclopedia.com)
  • If a helical portion of a protein contained 36 amino acids, there would be 10 complete turns in the helix. (encyclopedia.com)
  • The α helix is the most abundant type of secondary structure in proteins. (wikipedia.org)
  • A purine base always pairs with a pyrimidine base (guanine (G) pairs with cytosine (C) and adenine (A) pairs with thymine (T) or uracil (U)). DNA's secondary structure is predominantly determined by base-pairing of the two polynucleotide strands wrapped around each other to form a double helix. (wikipedia.org)
  • Structurally
  • How are proteins used Structurally? (brainscape.com)
  • In the present study, we build on these previous results, and investigate the consequences of chemokine receptor heteromerization with ChemR23, the receptor of chemerin, a leukocyte chemoattractant protein structurally unrelated to chemokines. (nih.gov)
  • Cysteine
  • Cysteine on the other hand can react with another cysteine residue and thereby form a cross link stabilizing the whole structure. (wikipedia.org)
  • biochemical
  • hRSV M2-1 is a tight tetramer bearing a Cys3-His1 zinc-binding motif, present in Ebola VP30 protein and some eukaryotic proteins, whose integrity was shown to be essential for protein function but without a biochemical mechanistic basis. (conicet.gov.ar)
  • relatively
  • Because the resolution of the apoptosome structure was relatively low, two controversial models for apoptosome assembly were proposed. (wikipedia.org)
  • covalently attached
  • It is also called a conjugate vaccine, in which a polysaccharide antigen has been covalently attached to a carrier protein for T-cell-dependent antigen processing (utilizing MHC II). (wikipedia.org)
