The phrase "are rate limiting" is correct and usable in written English.
It is typically used in contexts related to processes or factors that restrict or control the rate of a particular action or reaction, often in scientific or technical discussions.
Example: "In biochemical reactions, certain enzymes are rate limiting, determining the speed at which the reaction occurs."
Alternatives: "are constraining" or "are restricting the rate".
Arginine plasma levels are rate limiting for NO synthesis, and low arginine plasma levels are seen after major vascular surgery.
Hydrolysis reactions of lignocellulose fiber are rate limiting because of physicochemical and compositional factors in the structure of fiber (Kumar et al. 2009; Noike et al. 1985).
Second, factors that are rate limiting for OXPHOS activity are not affected by the Delg mutation.
These findings suggest that BMI1 and MEL18 are rate limiting for repression of INK4a by mCbx7.
RNAi against either hep or Mkk4 reduces JNK activation upon commercial LPS treatment (Figure 3A) suggesting that both kinases are rate limiting in this situation.
Cold induced expression of PGC1α stimulates transcription of metabolic enzymes such as cytochrome c oxidase and F0F1-ATPase, which are rate limiting steps in oxidative phosphorylation [30].
In fact, there is no agreement even as to which step(s) are rate-limiting.
The contributions of mass transfer and intrinsic adsorption kinetics to the overall rate were estimated, and it has been found that the adsorption kinetics are rate-limiting.
Although chloroplasts have the machinery to produce and assemble these complex proteins with multiple disulfide bonds (Tran et al. 2013a, b), little has been done to determine which steps of complex protein accumulation are rate-limiting.
Thus, at low concentration, the association steps are rate-limiting only in the reassembly of CtxB5.
Cyclooxygenases (COX-1 and -2) are rate-limiting enzymes in the production of prostaglandins (PGs) from arachidonic acid.
