Microbial growth with a carbohydrate as the sole carbon source is thus possible only if a cellular process occurs that effects the net formation of some TCA cycle intermediate from an intermediate of carbohydrate catabolism.
Because the TCA cycle is initiated by the condensation of acetyl coenzyme A with oxaloacetate, which is regenerated in each turn of the cycle, the removal of any intermediate from the cycle would cause the cycle to stop.
Weak rock masses normally refer to low strength, highly fractured decomposed and tectonically disturbed rocks which have properties intermediate from brittle rocks to ductile soils.
Strictosidine glucosidase (SGD) from Catharanthus roseus catalyzes the deglycosylation of strictosidine, an intermediate from which thousands of monoterpene indole alkaloids are derived.
This study aims at the evolution of coke formation on various catalysts in the catalytic conversion of furan as an important intermediate from biomass fast pyrolysis.
RH was found as the principal parameter that affect significantly the mineralization and the formation of acetone, the principal reaction intermediate from the photocatalytic oxidation of 2-propanol.
In addition, an intermediate (from 5 to 13-fold) down-regulation of MASP was observed in skin and liver samples at 36 and 48 h pi with respect to control fish.
MMI1 (unadjusted metrics) performed better than MMI2 (natural variation-adjusted metrics) in discriminating least- and most-disturbed sites, but MMI2 distinguished intermediate from most-disturbed sites better than MMI1.
Molecular analysis of the ∼37 kb locus and structure elucidation of a linear pathway intermediate from an engineered mutant reveal that the unusual bis-lactone aglycone chartarin is derived from an anthracycline-type polyketide.
Substrate channeling is a process of transferring an intermediate from one enzyme to the next enzyme without diffusion into the bulk phase, thereby leading to an enhanced reaction rate.
Acetate was obtained as a major metabolic intermediate from the degradation of glucose and a shift in the biochemical pathway towards formation of butyrate occurred after maximum substrate degradation.
