  • tissues
  • Concentrations of glycolytic intermediates were altered by adding 2mM iodoacetic acid (IAA) to an incubation medium containing tissues isolated from the channelled whelk Busycon canaliculatum. (carleton.ca)
  • activity
  • Iodoacetic acid inhibited glyceraldehyde 3-phosphate dehydrogenase activity causing a 100-400 fold increase in the concentration of fructose 1,6-bisphosphate as well as 3-20 fold increases in glucose 6-phosphate, fructose 6-phosphate, and dihydroxyacetone phosphate levels depending on the experimental protocol.

  • Cysteine
  • The cleavage reaction proceeded in a time-dependent manner and was optimal when incubated at 25°C. I7L-mediated cleavage was not affected by selected inhibitors of metalloproteinases, aspartic acid proteinases or serine proteinases (EDTA, pepstatin, and PMSF, respectively), but was sensitive to several general cysteine proteinase inhibitors (E-64, EST, Iodoacetic acid, and NEM) as well as the I7L active site inhibitor TTP-6171 [C. Byrd et al . (biomedcentral.com)
  • Hydrolysis involves usually a catalytic triad consisting of the thiol group of the cysteine, the imidazolium ring of a histidine, and a third residue, usually asparagine or aspartic acid, to orientate and activate the imidazolium ring. (ebi.ac.uk)
  • In only one family of cysteine peptidases, is the role of the general base assigned to a residue other than a histidine: in peptidases from family C89 (acid ceramidase) an arginine is the general base. (ebi.ac.uk)
  • ENZYMES
  • In general, C69 family is variable in sequence and exhibits great diversity in substrate specificity, to include enzymes such as choloyglycine hydrolases, acid ceramidases, isopenicillin N acyltransferases, and a subgroup of eukaryotic proteins with unclear function. (ebi.ac.uk)
  • Iodoacetic acid, an inhibitor of GAPDH, eliminated 45 Ca transport supported by fructose-1,6-diphosphate, the substrate for aldolase, but transport was completely restored by phosphoenolpyruvate (the substrate for PK), indicating that both of the ATP-producing glycolytic enzymes, GAPDH/PGK and PK, were associated with the SR and functionally capable of providing ATP for the Ca 2+ pump.

  • amino acid
  • Why aren't amino acid substitutions listed in the search form? (matrixscience.com)
  • Amino acid substitutions are rare and there are lots of them, so the only practical way to use them is in an error tolerant search. (matrixscience.com)
  • If the protein is not known in the UniProtKB/Swiss-Prot and UniProtKB/TrEMBL databases, you can enter the sequence of your protein of interest, in single letter amino acid code, in either upper or lower case. (expasy.org)
  • interest
  • This invention discloses and provides improvements in analyzing transcription of mRNA in eukaryotic cells using nuclear runoff transcription assays, including analysis of nuclear runoff transcription products by microarrays containing genes of interest, e.g. microarrays of nucleic acid molecules representing a genome of interest.
