The phrase "act on the substrate" is correct and usable in written English.
It can be used in scientific or technical contexts, particularly in biology or chemistry, to describe the interaction of an enzyme or catalyst with a substrate.
Example: "The enzyme will act on the substrate to facilitate the chemical reaction."
Alternatives: "interact with the substrate" or "perform on the substrate".
SDRs act on the substrate by transferring electrons from or to coenzyme.
Further disaggregation by enzymes and microflora act on the substrate occurs during the passage in the gut of the earthworm (Edwards and Bohlen 1996).
Characteristics such as its high thermostability allow the MpXyn10A to act on the substrate for long periods, allowing a more complete hydrolysis of the substrate.
The enzyme would also have to act on the substrate twice for there to be a detectable change in the optical density (OD), as diacylglycerol would not be solubilised and therefore not reduce the OD.
The high thermostability of the enzyme allows it to act on the substrate for prolonged periods, which presents clear advantages for the production of higher amounts of fermentable sugars from pretreated sugar cane bagasse.
In contrast, the oxidative proteins that act on the substrate do so through a direct catalytic oxidative mechanism, where radical species are generated in close proximity to the cellulose surface, resulting in the direct oxidative cleavage of the cellulose chains [ 33- 38].
At the top of the phenylpropanoid pathway, phenylalanine lyase acts on the substrate L-phenylalanine, and converts it to cinnamate (often, trans-cinnamate) which is then oxidized to p-coumarate by the enzyme cinnamate 4-hydroxylase.
DOIS acts on the substrate glucose 6-phosphate [G6P] and is not as well studied, but structures of it have been determined in the presence and absence of carbaglucose 6-phosphate (CG6P), a mechanism-based inhibitor.
DHQS acts on the substrate 3-deoxy d-arabinoheptulosonate 7-phosphate [DAHP] as part of aromatic amino acid biosynthesis and has been well-studied because it is a target for antimicrobial drug development.
In the periplasmic compartment, substrate proteins with misoxidized disulfide bonds are shuffled to properly oxidized states by two mechanisms: (1) the isomerase pathway, where DsbC acts on the substrate as reductase-oxidase, and (2) the reductase pathway, where DsbC simply acts as reductase, allowing DsbA another chance to correctly oxidize the substrate [ 43].
It might be possible that STT3A and STT3B act differently on the substrate selection and even the occurrence of N-linked protein modification in plants, which conferred different types of N-glycans on the substrate peptides.
