 Context examples 


While not absolutely required for catalysis of nucleotide exchange, the PH domain appears to greatly increase catalytic efficiency in many cases.

(DH Domain, NCI Thesaurus)

This protein plays a role in the catalysis of phosphorylation of phosphatidylinositol-4-phosphate to form phosphatidylinositol-4,5-biphosphate, the precursor to second messengers of phosphoinositide signal transduction pathways.

(Phosphatidylinositol 5-Phosphate 4-Kinase Type-2 Alpha, NCI Thesaurus)

It is therefore surprising that catalysis, which is known to be so useful in so many fields, is practically unheard-of in oncology.

Lipid Binding is the molecular interaction between a lipid molecule and a macromolecule (usually protein) for transport, catalysis, localization, or modification of function.

(Lipid Binding, NCI Thesaurus)

This protein is involved in the catalysis of protein neddylation.

(NEDD8-Activating Enzyme E1 Catalytic Subunit, NCI Thesaurus)

Peldesine inhibits purine nucleoside phosphorylase (PNP) that plays a pivotal role in T-cell proliferation and is responsible for the catalysis of the reversible phosphorolytic cleavage of purine ribonucleosides and 2'-deoxyribonucleosides.

(Peldesine, NCI Thesaurus)

CRE Recombinase catalyses site-specific recombination between two 34 base pair loxp sites and maintains the phage genome as a monomeric unit-copy plasmid in the lysogenic state.

(CRE Recombinase, NCI Thesaurus)

Phospholipid Interaction involves the molecular interaction between a phospholipid molecule and a macromolecule (usually protein) for transport, catalysis, localization, or modification of function.

(Phospholipid Binding, NCI Thesaurus)

Unlike TS inhibitors, this agent is a reversible substrate for TS catalysis.

(Brivudine Phosphoramidate, NCI Thesaurus)

This protein plays a role in the catalysis of the side-chain cleavage reaction converting cholesterol to pregnenolone.
