Moonlighting proteins

Fructose-bisphosphate aldolase (EC 4.1.2.13), often just aldolase, is an enzyme catalyzing a reversible reaction that splits the aldol, fructose 1,6-bisphosphate, into the triose phosphates dihydroxyacetone phosphate (DHAP) and glyceraldehyde 3-phosphate (G3P).

In enzymology, glutamate racemase (MurI with a capital i) (EC 5.1.1.3) is an enzyme that catalyzes the chemical reaction L-glutamate D-glutamate Hence, this enzyme RacE has one substrate, L-glutamate, and one product, D-glutamate.

Galactokinase is an enzyme (phosphotransferase) that facilitates the phosphorylation of α-D-galactose to galactose 1-phosphate at the expense of one molecule of ATP.

Heat shock proteins are generally responsible for preventing damage to proteins in response to high levels of heat.

A hexokinase is an enzyme that phosphorylates hexoses (six-carbon sugars), forming hexose phosphate.

Aconitase (aconitate hydratase; EC 4.2.1.3) is an enzyme that catalyses the stereo-specific isomerization of citrate to isocitrate via cis-aconitate in the tricarboxylic acid cycle, a non-redox-active process.

Pyruvate carboxylase (PC) is an enzyme of the ligase class that catalyzes (depending on the species) the physiologically irreversible carboxylation of pyruvate to form oxaloacetate (OAA).

Heat shock 10 kDa protein 1 (Hsp10) also known as chaperonin 10 (cpn10) or early-pregnancy factor (EPF) is a protein that in humans is encoded by the HSPE1 gene.

Presenilins are a family of related multi-pass transmembrane proteins which constitute the catalytic subunits of the gamma-secretase intramembrane protease complex.

In anatomy, a crystallin is a water-soluble structural protein found in the lens and the cornea of the eye accounting for the transparency of the structure.

Phosphofructokinase is a kinase enzyme that phosphorylates fructose 6-phosphate in glycolysis.

Enolase, also known as phosphopyruvate hydratase, is a metalloenzyme responsible for the catalysis of the conversion of 2-phosphoglycerate (2-PG) to phosphoenolpyruvate (PEP), the ninth and penultimate step of glycolysis.
