The phrase "a heterotetramer comprising" is correct and usable in written English.
It can be used in scientific or technical contexts, particularly in biochemistry or molecular biology, to describe a complex made up of four different subunits.
Example: "The study focused on a heterotetramer comprising two different proteins and two different peptides, which play a crucial role in cellular signaling."
Alternatives: "a heterotetramer consisting of" or "a heterotetramer made up of".
The eukaryotic GINS forms a heterotetramer, comprising four types of subunits.
These three polypeptides form a heterotetramer comprising two Idh3α subunits, one Idh3β and one Idh3γ subunit [ 29].
Yeast protein kinase A is a heterotetramer comprising two identical regulatory subunits, encoded by BCY1, and two catalytic subunits, encoded by three related genes, TPK1, TPK2, and TPK3.
ADP-glucose pyrophosphorylase (AGPase), which catalyses a rate limiting step in starch synthesis, is a heterotetramer comprised of two identical large and two identical small subunits in plants.
The NMJ glutamate receptor (GluR) is a heterotetramer comprised of three invariant subunits: GluRIIC, D, and E. The fourth subunit, either GluRIIA or B, determines the type and the electrophysiological properties of the receptor (DiAntonio et al., 1999; Featherstone et al., 2005; Qin et al., 2005a; DiAntonio, 2006).
Adducin normally functions as a heterodimer or heterotetramer comprised of α/β or α/γ subunits that serve to cap and bundle actin filaments, and recruit spectrin.
It has also been reported that PTPC is monoubiquitinated in COS, resulting in a Class-1 PEPC heterotetramer comprised of Ub-PTPC PTPC [ 11].
This heterotetramer comprises two identical large and two identical small subunits.
O. tauri and potato tuber enzymes were heterotetramers comprising homologous small and large subunits.
Heterotetramers comprising untagged WT and FT2·WT TTR subunits also appear to exhibit identical kinetics of tetramer dissociation and reassociation.
The variability in the age of onset or the aggressiveness of the hereditary TTR amyloidoses can, in part, be attributed to differences in the thermodynamic and kinetic stability of heterotetramers comprising disease-associated and WT TTR subunits.
