Catalysis of the reaction: ATP + L-tryptophan + tRNA(Trp) = AMP + diphosphate + L-tryptophanyl-tRNA(Trp).

regulation of long-term neuronal synaptic plasticity

A process that modulates long-term neuronal synaptic plasticity, the ability of neuronal synapses to change long-term as circumstances require. Long-term neuronal synaptic plasticity generally involves increase or decrease in actual synapse numbers.

Catalysis of the reaction: ATP + L-tyrosine + tRNA(Tyr) = AMP + diphosphate + L-tyrosyl-tRNA(Tyr).

Catalysis of the reaction: ATP + L-valine + tRNA(Val) = AMP + diphosphate + L-valyl-tRNA(Val).

Catalysis of the reaction: L-tryptophan + O2 = L-formylkynurenine.

Catalysis of the reaction: ATP + detyrosinated alpha-tubulin + L-tyrosine = alpha-tubulin + ADP + phosphate.

positive regulation of steroid metabolism

Any process that activates or increases the rate of the chemical reactions involving steroids.

mitochondrial electron transport, NADH to ubiquinone

oxidative phosphorylation, NADH to ubiquinone

The transfer of electrons from NADH to ubiquinone that occurs during oxidative phosphorylation, mediated by the multisubunit enzyme known as complex I.

Catalysis of the reaction: L-tyrosine + 2-oxoglutarate = 4-hydroxyphenylpyruvate + L-glutamate.

The excessive phosphorylation of a protein, as a result of activation of kinases, deactivation of phosphatases, or both.

Any process that activates or increases the rate of transcription.

Catalysis of the activation of the C-terminal carboxyl group of ubiquitin by the formation of a high-energy thioester bond in an ATP-dependent manner.

mitochondrial electron transport, ubiquinol to cytochrome c

complex III (ubiquinone to cytochrome c)

The transfer of electrons from ubiquinol to cytochrome c that occurs during oxidative phosphorylation, mediated by the multisubunit enzyme known as complex III.

Interacting selectively with S100 beta protein. S100 is a small calcium and zinc binding protein produced in astrocytes that is implicated in Alzheimer's disease, Down Syndrome and ALS.
