(1) It appears to be due, in large part, to the activity of a specific enzyme , cytokinin oxidase.

(2) The enzymic pathways shown will not necessarily all be present in a particular cell.

(3) The enzymatic removal of carbohydrate has been successful with soluble proteins.

(4) The enzymatic degradation of a phospholipid membrane has been followed in situ.

(5) An alternative approach is to enzymatically remove interfering carbohydrate from naturally abundant eukaryotic membrane proteins.

(6) In addition, steroid hormones are known to impair enzymic antioxidant defenses and directly induce oxidative stress.

(7) Water molecules play an active role in the regulation of protein and enzymatic reactivity.

(8) Nevertheless, it is known that fish peroxisomes have enzymatic systems similar to those reported in mammals.

(9) Consequently, we examined the interaction between the two proteins in extracts without enzymatically digesting the cellular DNA.

(10) It is clear that cells have a variety of relatively specific enzymes able to degrade these compounds.

(11) During blood clotting, two peptide fragments are removed enzymatically from fibrinogen in the formation of fibrin, the blood-clotting protein.

(12) Conversely, the hydrophilic amino acids are generally found on the exterior of proteins as well as in the active centers of enzymatically active proteins.

(13) They can act as real enzymes and, by analogy to protein enzymes , are called ribozymes.

(14) This effect was independent of the enzymatic activity of this protein.

(15) The phototoxic activity of this porphyrin is mainly mediated by the impairment of the enzymic and transport functions of both the outer and cytoplasmic membranes.

(16) For enzymic catalysis, this source of reversible work is unlikely because the amount of work required is much greater, while the participants in the reaction, including the enzyme, are usually chemically unreactive.

(17) Among these anaerobic proteins are enzymes involved in glycolysis and related processes.

(18) On the one hand, they may simply be by-products of several enzymic reactions.

(19) They are defined as carbohydrate-binding proteins which are distinct from immunoglobulins, do not enzymatically alter the structure of their ligands, and do not act as sensor/transport proteins for free mono- or disaccharides.

(20) This is probably due to the presence of other enzymes besides the protease.
