T1 | 0-105 | Sentence | denotes | Identification and modification of the uridine-binding site of the UDP-GalNAc (GlcNAc) pyrophosphorylase. |
T2 | 106-218 | Sentence | denotes | UDP-GalNAc pyrophosphorylase (UDP-GalNAcPP; AGX1) catalyzes the synthesis of UDP-GalNAc from UTP and GalNAc-1-P. |
T3 | 219-327 | Sentence | denotes | The 475-amino acid protein (57 kDa protein) also synthesizes UDP-GlcNAc at about 25% the rate of UDP-GalNAc. |
T4 | 328-511 | Sentence | denotes | The cDNA for this enzyme, termed AGX1, was cloned in Escherichia coli, and expressed as an active enzyme that cross-reacted with antiserum against the original pig liver UDP-HexNAcPP. |
T5 | 512-663 | Sentence | denotes | In the present study, we incubated recombinant AGX1 with N(3)-UDP-[(32)P]GlcNAc and N(3)-UDP-[(32)P]GalNAc probes to label the nucleotide-binding site. |
T6 | 664-869 | Sentence | denotes | Proteolytic digestions of the labeled enzyme and analysis of the resulting peptides indicated that both photoprobes cross-linked to one 24-amino acid peptide located between residues Val(216) and Glu(240). |
T7 | 870-1023 | Sentence | denotes | Four amino acids in this peptide were found to be highly conserved among closely related enzymes, and each of these was individually modified to alanine. |
T8 | 1024-1261 | Sentence | denotes | Mutation of Gly(222) to Ala in the peptide almost completely eliminated UDP-GlcNAc and UDP-GalNAc synthesis, while mutation of Gly(224) to Ala, almost completely eliminated UDP-GalNAc synthesis, but UDP-GlcNAc was only diminished by 50%. |
T9 | 1262-1426 | Sentence | denotes | Both of these mutations also resulted in almost complete loss of the ability of the mutated proteins to cross-link N(3)-UDP-[(32)P]GlcNAc or N(3)-UDP-[(32)P]GalNAc. |
T10 | 1427-1643 | Sentence | denotes | On the other hand, mutations of either Pro(220) or Tyr(227) to Ala did not greatly affect enzymatic activity, although there was some reduction in the ability of these proteins to cross-link the photoaffinity probes. |
T11 | 1644-1804 | Sentence | denotes | We also mutated Gly(111) to Ala since this amino acid was reported to be necessary for catalysis (Mio, T., Yabe, T., Arisawa, M., and Yamada-Okabe, H. (1998) J. |
T12 | 1805-1810 | Sentence | denotes | Biol. |
T13 | 1811-1816 | Sentence | denotes | Chem. |
T14 | 1817-1835 | Sentence | denotes | 273, 14392-14397). |
T15 | 1836-2034 | Sentence | denotes | The Gly(111) to Ala mutant lost all enzymatic activity, but interestingly enough, this mutant protein still cross-linked the radioactive N(3)-UDP-GlcNAc although not nearly as well as the wild type. |
T16 | 2035-2197 | Sentence | denotes | On the other hand, mutation of Arg(115) to Ala had no affect on enzymatic activity although it also reduced the amount of cross-linking of N(3)-UDP-[(32)P]GlcNAc. |
T17 | 2198-2366 | Sentence | denotes | These studies help to define essential amino acids at or near the nucleotide-binding site and the catalytic site, as well as peptides involved in binding and catalysis. |
