Binding of simple carbohydrates and some of their chromophoric derivatives to soybean agglutinin as followed by titrimetric procedures and stopped flow kinetics.
J. Biol. Chem. 259(11) , 7067-74, (1984) The number of carbohydrate-binding sites of the GalNAc-specific lectin is four per tetramer. The binding parameters of N-acetyl-D-galactosamine and methyl-N-acetyl-alpha-D- galactosaminide , were determined by titrating the perturbation in the absorption spec... |

Syntheses of the 3- and 4-thio analogues of 4-nitrophenyl 2-acetamido-2-deoxy-beta-D-gluco- and galactopyranoside.
Carbohydr. Res. 342(15) , 2212-22, (2007) The syntheses of 4-nitrophenyl beta-glycosides of the 3-thio and 4-thio analogues of the two principal 2-acetamido-2-deoxy-hexoses found in living systems, GlcNAc and GalNAc, are described. While synthesis of the 4-thio analogues could be achieved via nucleop... |

Chitin oligosaccharide synthesis by rhizobia and zebrafish embryos starts by glycosyl transfer to O4 of the reducing-terminal residue.
Biochemistry 38(13) , 4045-52, (1999) Lipochitin oligosaccharides are organogenesis-inducing signal molecules produced by rhizobia to establish the formation of nitrogen-fixing root nodules in leguminous plants. Chitin oligosaccharide biosynthesis by the Mesorhizobium loti nodulation protein NodC... |

Purification and characterization of beta-N-acetylhexosaminidase from Trichoderma harzianum.
Agric. Biol. Chem. 55(11) , 2817-23, (1991) beta-N-Acetylhexosaminidase was produced by Trichoderma harzianum cultivated with chitin as the growth substrate. The enzyme was purified 13.2-fold to homogeneity by ultrafiltration and sequential chromatography on SP-Toyopearl and Sephacryl S-200. The molecu... |

ZHOUPI controls embryonic cuticle formation via a signalling pathway involving the subtilisin protease ABNORMAL LEAF-SHAPE1 and the receptor kinases GASSHO1 and GASSHO2.
Cancer 49(1) , 128-35, (1982) Seed production in angiosperms requires tight coordination of the development of the embryo and the endosperm. The endosperm-specific transcription factor ZHOUPI has previously been shown to play a key role in this process, by regulating both endosperm breakd... |

Studies on the N-acetyl-beta-D-hexosaminidase B from germinating Lupinus luteus L. seeds. I. Purification and characterization.
Biochim. Biophys. Acta 1039(1) , 110-8, (1990) The N-acetyl-beta-D-hexosaminidase B of germinating Lupinus luteus L. seeds (McFarlane et al. (1984) Phytochemistry 23, 2431-2433) was partially purified with a six-step purification procedure following extraction. This enzyme consists of one protein chain (M... |

Purification and characterization of beta-N-acetylhexosaminidase from rice seeds.
J. Biochem. Mol. Biol. 35(3) , 313-9, (2002) N-Acetyl-beta-D-hexosaminidase (beta-HexNAc'ase) (EC 3.2.1.52) was purified from rice seeds (Oryza sativa L. var. Dongjin) using ammonium sulfate (80%) precipitation, Sephadex G-150, CM-Sephadex, and DEAE-Sephadex chromatography, sequentially. The activities ... |

Inactivation kinetics of beta-N-acetyl-D-glucosaminidase from green crab (Scylla serrata) in dioxane solution.
J. Biomol. Struct. Dyn. 26(4) , 509-15, (2009) Beta-N-acetyl-D-glucosaminidase (NAGase, EC.3.2.1.52), which catalyzes the cleavage of N-acetylglucosamine polymers, is a composition of chitinase and cooperates with endo-chitinase and exo-chitinase to disintegrate chitin into N-acetylglucosamine (NAG). In t... |

Glycosidase activity in the post-ecdysial cuticle of the blue crab, Callinectes sapidus.
Comp. Biochem. Physiol. B Biochem. Mol. Biol. 128(4) , 683-90, (2001) We have previously demonstrated a marked change in sugar moieties of glycoproteins of the cuticle of the blue crab, Callinectes sapidus, between 0.5 and 3 h post-ecdysis. The present study has identified a glycosidase that appears in the cuticle during the ea... |

Sulfation of p-nitrophenyl-N-acetyl-beta-D-galactosaminide with a microsomal fraction from cultured chondrocytes.
J. Biol. Chem. 260(24) , 13102-8, (1985) Chick embryo chondrocyte microsomes containing intact Golgi vesicles took up 3'-phosphoadenosine-5'-phospho[35S]sulfate ([35S]PAPS) in a time- and temperature-dependent, substrate-saturable manner. When [35S]PAPS and p-nitrophenyl-N-acetyl-beta-D-galactosamin... |
