The phrase "a more active form" is correct and usable in written English.
You can use it when discussing variations or types of something that exhibit increased activity or engagement compared to others.
Example: "In this study, we will explore a more active form of exercise that can lead to better health outcomes."
Alternatives: "a more dynamic version" or "a more vigorous type".
Although the monoclinic sulfated zirconia has been demonstrated to show some activity for alkane isomerisation, the tetragonal phase is reported to be a more active form, especially at lower temperatures (Stichert et al. 2001).
To test whether mutation to negatively charged residues might mimic autophosphorylation at this position and perhaps create a more active form of eEF2K, we created eEF2K[T348D] and eEF2K[T348E] mutants and studied their activities.
It necessitates a more active form of participation than just looking".
PtRu pair sites nucleate a more active form of oxygen-containing species than RuRu pairs or Ru clusters.
There have already been suggestions that perhaps powered flight evolved multiple times in the dinosaurs and early birds, with perhaps several different groups making the final jump from gliding to a more active form of movement in the air.
Finasteride, which keeps testosterone from converting into a more active form, has been used since 1992 to treat benign prostatic hyperplasia, or enlarged prostate, a condition unrelated to prostate cancer.
Moxetumomab pasudotox is actually an improved, more active form of a predecessor recombinant immunotoxin, BL22 (also called CAT-3888), which produced complete remission in relapsed/refractory hairy cell leukemia (HCL), but had a <20 % response rate in chronic lymphoid leukemia (CLL) and ALL, which are noted for containing much lower numbers of CD22 [ 191, 192].
However, only tumors of Bcat mice (4 of 24) carried missense mutations in the ctnnb1 codons that substituted the regulatory serine residues at positions 37 and 38 (Table S2) to result in a stabilized, more active form of β-catenin.
Using an alternative expression and purification strategy, however, we obtained an apparently more active form of the Bam complex that, together with SurA, was both necessary and sufficient to promote the membrane integration of the EspP β domain and the translocation and cleavage of the EspP passenger domain.
Furthermore, it has been proposed that the N-terminal portion of the B chain (residues B1 B8) also experiences a change in conformation, from an extended and stable form, known as the T state to a less stable but more active form, known as the R state [47].
However, when the PERK arm of the UPR is activated by thapsigargin, PERK from haplotype B homozygote cells is more active in phosphorylating eIF2α when compared to PERK from cells homozygous for haplotype A. The haplotype that confers high risk for PSP produces the more active form of PERK, suggesting that activation of the UPR is pathogenic in PSP and not a protective response.
