<enzyme> Commercial preparation from staphylococcus which catalyses oxidation of reducing sugars such as glucose, galactose, fructose, mannose, maltose, lactose, maltotriose, maltotetraose, maltopentaose and maltohexaose Registry number: EC 1.1.- (26 Jun 1999) |
oligosaccharide-diphosphodolichol pyrophosphatase |
<enzyme> From yeast microsomal membranes; hydrolyses the pyrophosphate bond of oligosaccharide-pyrophosphodolichol into oligosaccharide phosphates plus dolicholphosphate Registry number: EC 3.6.1.44 Synonym: ols-pp-dol pyrophosphatase, oligosaccharide-pyrophosphodolichol pyrophosphatase (26 Jun 1999) |
oligosaccharin |
<biochemistry> An oligosaccharide derived from the plant cell wall that in small quantities induces a physiological response in a nearby cell of the same or a different plant and thus acts as a molecular signal. Sometimes considered to be a plant hormone or plant growth substance. The best authenticated examples are involved in host pathogen interactions and in the control of plant cell expansion. (18 Nov 1997) |
