  • proteases
  • The existence of this seventh catalytic type of proteases, in which the peptide bond cleavage occurs by self-processing instead of hydrolysis, was demonstrated with the discovery of the crystal structure of the self-cleaving precursor of the Tsh autotransporter from E. coli. (wikipedia.org)
  • As an example, one may consider proteases (enzymes that aid digestion by causing hydrolysis of peptide bonds in proteins). (wikipedia.org)
  • conditions
  • The TBDPS group is prized for its increased stability towards acidic conditions and nucleophilic species over the other silyl ether protecting groups. (wikipedia.org)
  • 33, 3077-3080 and (1993), WO 93/16118) resins are cleaved in nucleophilic conditions (e.g. hydrolytic) as TENTAGEL® (Bayer, (1990), U.S. Pat. (google.com)
  • groups
  • 53, 19, 2975-2977, 1975 The novel features that they highlight are the increased resistance to acidic hydrolysis and increased selectivity towards protection of primary hydroxyl groups. (wikipedia.org)
  • electrophilic
  • Electron withdrawing groups at the ⍺-position Below is a list of steps involved in transforming a generic nitrile compound with nitrilase: The electrophilic carbon of the nitrile is subject to nucleophilic attack by one of the two SH groups on nitrilase. (wikipedia.org)
  • The processing temperatures can range from 350 to 430 °C. Plastics that fall within this family include: PEK PEEK PEKK PEEKK PEKEKK (polyetherketoneetherketoneketone) PAEKs can be produced in two ways, one is called the nucleophilic route and the other is called the electrophilic route. (wikipedia.org)
  • ester
  • These reactions follow similar routes involving an initial N-O or N-S acyl shift starting with a nucleophilic attack by a hydroxyl or thiol group on a carbonyl carbon followed by resolution of the ester intermediate. (openthesis.org)
  • enzymes
  • Lactase (also known as lactase-phlorizin hydrolase, or LPH), a part of the β-galactosidase family of enzymes, is a glycoside hydrolase involved in the hydrolysis of the disaccharide lactose into constituent galactose and glucose monomers. (wikipedia.org)
