The phrase "active type" is correct and usable in written English.
It can be used in contexts related to grammar, programming, or any field where types or categories are being discussed, particularly to describe something that is currently in use or functioning.
Example: "In our analysis, we found that the active type of the variable was causing unexpected behavior in the program."
Alternatives: "current type" or "operational type".
One XMRV-positive BAL specimen showed an 8-fold increase above background of specific type C retroviral reverse-transcriptase activity, suggesting presence of active type C retrovirus within this sample.
Only R-SMADs are targeted for activation via phosphorylation by the active type I receptor kinase.
Upon receptor oligomerization, the type I receptor is phosphorylated at its intracellular glycine-serine-rich domain (the so-called GS box) by the constitutively active type II receptor kinase thereby activating the SMAD signalling cascade affecting transcription of responsive genes in the nucleus [6].
Insoluble (e.g. "cell wall-bound") acid invertase (IAI) activity was, in general, the most active type of invertase detected in Ac plants.
TGF-β, after binding with specific receptors, induces the formation of a type II type I receptor complex, in which the constitutively active type II receptor (TβRII) phosphorylates and activates the type I receptor (TβRI).
These two isoforms are the only active type 1 ACS proteins, making them phosphorylation targets of mitogen-activating protein kinase (MAPK) MPK3/MPK6.
We report on a high resolution X-ray diffraction analysis of three antimonide-based mid-infrared laser samples (designed for optical pumping) with an active type-II structure.
The other prime pathology associated with COPD is small airway fibrosis and obliteration, and this could potentially be related to active Type-II EMT at this site, if such would be demonstrated [8]-[11].
The chancellor of the exchequer, Gordon Brown, hitherto a seriously hyper-active type, needed a break from using fiscal policy to mend every last thing in the economy that does not work exactly as he thinks it should, and so did the country.
Drugs may be metabolized when transported via airway epithelial cells, Clara cells or via metabolically-active type II pneumocytes.
Compared to the healthy skin, ILC2s are increased in the skin of patients with atopic dermatitis (Kim et al., 2013; Salimi et al., 2013), suggesting that ILC2s are involved in atopic dermatitis, an inflammatory disease associated with over-active type 2 immune responses to environmental allergens and barrier dysfunction (Leung, 2013).
