The phrase "act to form" is not a standard expression in written English and may cause confusion.
It could be used in contexts where one is discussing taking action to create or establish something, but it is not commonly recognized.
Example: "In order to address the issue, we must act to form a committee that will oversee the project."
Alternatives: "take steps to create" or "move to establish".
Such enzymes, whose ability to catalyze a reaction depends upon molecules other than their substrates (the ones upon which they act to form a product), are said to be under allosteric control.
These groups together can synergistically act to form strong intermolecular interactions, which lead to tubular or fibrous structures (Fig. 4b).
ABS focuses on agents' properties and processes, responsible for responding to external changes, specifically how agents can "sense" and "act" to form a complex system.
These factors act to form regions on the cornea that map an image to different locations on the retina.
Indeed, it has been recently shown that Smad3 and Ets-1 co-immunoprecipitate and act to form a transcriptionally active complex with the transcriptional cofactor p300 [ 28].
In whipped cream the fat globules reach a partial coalesced state and act to form a solid-like network that gives the whipped cream its physical stability.
The interaction changes the shape of the enzyme so as to affect the formation at the active site of the usual complex between the enzyme and its substrate (the compound upon which it acts to form a product).
In induction, synthesis of a specific enzyme, called an inducible enzyme (e.g., β-galactosidase in Escherichia coli), occurs when cells are exposed to the substance (substrate) upon which the enzyme acts to form a product.
Inhibition, in enzymology, a phenomenon in which a compound, called an inhibitor, in most cases similar in structure to the substance (substrate) upon which an enzyme acts to form a product, interacts with the enzyme so that the resulting complex either cannot undergo the usual reaction or cannot form the usual product.
Cooperativity, in enzymology, a phenomenon in which the shape of one subunit of an enzyme consisting of several subunits is altered by the substrate (the substance upon which an enzyme acts to form a product) or some other molecule so as to change the shape of a neighbouring subunit.
The reaction between an enzyme and its substrate defined as the compound with which the enzyme acts to form a product occurs at a specific site on the enzyme known as the catalytic, or active, site; the proper fit between the substrate and the active site is an essential prerequisite for the occurrence of a reaction catalyzed by an enzyme.
