What's the difference between cleavage and parting?

Cleavage


Definition:

  • (n.) The act of cleaving or splitting.
  • (n.) The quality possessed by many crystallized substances of splitting readily in one or more definite directions, in which the cohesive attraction is a minimum, affording more or less smooth surfaces; the direction of the dividing plane; a fragment obtained by cleaving, as of a diamond. See Parting.
  • (n.) Division into laminae, like slate, with the lamination not necessarily parallel to the plane of deposition; -- usually produced by pressure.

Example Sentences:

  • (1) It is possible that the high level of radiolabeled phospholipid found in the plasma membrane arose via the de novo pathway following the cleavage of an acyl group as we have found cytidine diphosphocholine phosphotransferase in the plasma membrane fraction (Wang, P., DeChatelet, L.R., and Waite, M. (1977) Biochim.
  • (2) Release of nsP4 from P1234 appears to be independent of the other cleavages and occurs primarily immediately after translation.
  • (3) A broad specificity of LipDH was observed for the glycine cleavage system.

  • (5) One of the proteases obtained was found to catalyse cleavage on the COOH-side of peptide sequences containing consecutive hydrophobic and basic residues.
  • (6) The results show that in both viral DNAs cleavage occurs at the origin and at one additional site which shows striking sequence homology with the origin region.
  • (7) These results would suggest that N-terminal acetylation and C-terminal proteolytic cleavage are important post-translational modifications of the forms of Amia beta-endorphin.
  • (8) We speculate that this cleavage event is catalyzed by either a cryptic potyviral proteinase that requires a host factor or subcellular environment for activation, or possibly a host proteinase.

  • (16) The cleavage of beta-cyclodextrine by sodium periodate at the seven 2-3 diols of the glucose unit gives rise to the polyaldehyde 1, used to modify alpha-amylase.
  • (17) The possibility that mammalian DNA topoisomerase II is an intracellular target which mediates drug-induced DNA breaks is supported by the following studies using 4'-(9-acridinylamino)methane-sulfon-m-anisidide (m-AMSA): (a) a single m-AMSA-dependent DNA cleavage activity copurified with calf thymus DNA topoisomerase II activity at all chromatographic steps of the enzyme purification; (b) m-AMSA-induced DNA cleavage by this purified activity resulted in the covalent attachment of protein to the 5'-ends of the DNA via a tyrosyl phosphate bond.
  • (18) This single substitution was sufficient to abolish all detectable cleavage of the gp160 envelope precursor polypeptide as well as virus infectivity.
  • (19) Certain RNA molecules can mediate their own cleavage or splicing or act as enzymes to promote reactions on substrate RNA molecules.
  • (20) The envelope glycoprotein of human immunodeficiency virus consists of two subunits, designated gp120 and gp41, derived from the cleavage of a precursor polypeptide gp160.

  • (6) Because cystine in medium was converted rapidly to cysteine and cysteinyl-NAC in the presence of NAC and given that cysteine has a higher affinity for uptake by EC than cystine, we conclude that the enhanced uptake of radioactivity was in the form of cysteine and at least part of the stimulatory effect of NAC on EC glutathione was due to a formation of cysteine by a mixed disulfide reaction of NAC with cystine similar to that previously reported for Chinese hamster ovarian cells (R. D. Issels et al.
