Northern peatlands are substantial carbon sinks because organic matter in peat is highly stable due to the low rate of decomposition. Waterlogged anaerobic conditions induce accumulation Sphagnum -derived phenolic compounds that inhibit decomposition, a mechanism referred as “enzymic latch”. Recent studies have predicted water table northern may become unstable. We observed such unstable levels...
The nature and enzymic properties of starch-branching enzyme (SBE) are two of the dominant factors influencing the fine structure of starch. To understand the role of this enzyme's activity in the formation of starch in kidney bean (Phaseolus vulgaris L.), a study was undertaken to identify the major SBE sequences expressed during seed development and to characterize the enzymic properties of t...

Antioxidant activity of ethanolic extract of fruits of Terminalia chebula (500 mg/kg body wt, orally for 30 days) against isoproterenol-induced oxidative stress was investigated in rats. The levels of serum lipid peroxides, iron, ascorbic acid, vitamin E, plasma iron-binding capacity, and the activities of ceruloplasmin and glutathione were assayed, in addition to the activities of the antioxid...
Particulate, and digitonin-solubilized, enzyme systems from Phaseolus aureus and Lupinus albus catalyze the biosynthesis of aqueous-insoluble glucans from UDP-d-glucose. The digitonin treatment greatly increases the enzymic activity of (per unit protein) both the 34,000g pellet and the supernatant liquid as compared with that of the original particles. Most of the polymer produced (90-95%) is s...
