Known Functions

Amino Acid Metabolism

- transamination

- transsulfuration

- selenoamino acid metabolism

- conversion of typtophan to niacin.

Gluconeogenesis

- Catalyse transamination reactions for gluconeogenesis.

- Coenzyme for glycogen phosphorylase, which catalyse glycogenolysis.

Neurotransmitter Synthesis

- Coenzyme for Pyridoxal phosphate-dependent enzymes, which catalyses the biosynthesis of serotonin, epinephrine, norepinephrine and gamma-aminobutyric acid(The four important neurotranmsitters).

Histamine Synthesis

- Metabolism of histamine.

Hemoglobin Synthesis and Function

- Synthesis of heme

- Binds to two sites on hemoglobin, enhancing the oxygen binding of hemoglobin.

Gene Expression

- Increases or decreases the expression of certain genes.

Functional Prediction:

Cofactor of HSPD1 and play a role in protein folding.

Coenzyme for asparagine synthetase by interacting with TS11.
