ADPglucose pyrophosphorylase (glucose-1-phosphate adenylyltransferase; ADP:alpha-D-glucose-1-phosphate adenylyltransferase, EC 2.7.7.27) catalyzes a key regulatory step in alpha-glucan synthesis in bacteria and higher plants. We have previously shown that the expression of the cDNA sequences of the

Sweet potato starch residue (SPSR) was used as starting material to prepare an eco-friendly adsorbent. SPSR was modified by bromoacetyl bromide to obtain a macroinitiator for surface-initiated single electron transfer-living radical polymerization (SI-SET-LRP) of acrylonitrile (AN) catalyzed by

Commercial pectin (with a 94% degree of esterification, DE94) suspended in methanol was reacted with methanolic alkaline hydroxylamine at room temperature for 20 h to prepare pectin hydroxamic acids (PHAs). The prepared PHA was coupled to the epoxy-activated Sepharose 6B gel to get immobilized PHA

Maturation of potato (Solanum tuberosum L.) tuber native and wound periderm and development of resistance to periderm abrasion were investigated utilizing cytological and histochemical techniques. Both native and wound periderm consist of three different tissues: phellem, phellogen and phelloderm.

The removal of pyridoxal 5'-phosphate from potato phosphorylase [EC 2.4.1.1] was achieved by incubation in an acidic ammonium sulfate solution containing hydroxylamine. Potato apophosphorylase is catalytically inactive, but reactivated by incubation with pyridoxal phosphate. Upon titration, the

ADP-glucose pyrophosphorylase (AGPase) is the allosterically regulated gateway for carbon entry into transient and storage starch in plants as well as glycogen in bacteria. This enzyme plays a key role in the modulation of photosynthetic efficiency in source tissues and directly determines the level

Diethyl pyrocarbonate (DEPC) in conditions that favour carbethoxylation of histidyl residues strongly inactivated E-type ATPase activity of a rat lung membrane preparation, as well as ecto-ATPase activity of rat vessels and human Epstein-Barr virus-transformed B lymphocytes. Inactivation of the

Aqueous extracts of a population of Ditylenchus dipsaci isolated from onion and maintained monoxenically on onion callus contained endo-polygalacturonase (endo-PG) and endo-pectinmethyltranseliminase (endo-PMTE). In viscometric tests pH 4.2 and 4.0 were optimal for degradation of sodium polypectate

Prions were purified from scrapie-infected hamster brains and incubated for 24 hr at 65 degrees with 2 mM Zn2+ or 5 mM Mg2+; no loss of infectivity was observed. Bacteriophage M13, tobacco mosaic virus (TMV), potato virus X, and potato spindle tuber viroid were all inactivated by divalent metal ions

Chitinase isolated from Zea mays seeds is inactivated by 1-ethyl-3-(3-dimethylaminopropyl)carbodiimide (EDC) in the absence of exogenous nucleophiles. Oligomers of N-acetylglucosamine,N,N',N",N"'-tetra-N-acetylchitotetraose (GlcNAc4), and to a lesser extent, N,N',N"-tri-N-acetylchitotriose (GlcNAc3)
