Stops, prevents or reduces the activity of any enzyme that catalyzes the hydrolysis of GTP to GDP and orthophosphate.

Increases the activity of a GTPase, an enzyme that catalyzes the hydrolysis of GTP.

The joining of the sister chromatids of a replicated chromosome along the entire length of the chromosome that occurs during meiosis.

A change in state or activity of an organism as the result of exposure to a xenobiotic compound, a compound foreign to living organisms.

The processes by which a substance or cellular entity, such as a protein complex or organelle, is transported to, and/or maintained in, a specific location.

Increases the rate of GTP hydrolysis by the GTPase Ras.

A change in state or activity of an organism (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of the perception of a photon of UV light.

A change in state or activity of the organism (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of the perception of a light stimulus.

synaptic growth at neuromuscular junction

The growth of a synapse at a neuromuscular junction, the site of apposition of a motor end plate and the subneural cleft of the skeletal muscle fiber that it innervates.

regulation of cell organization and biogenesis

regulation of cell organisation and biogenesis

Any process that modulates the frequency, rate or extent of the processes involved in the assembly and arrangement of cell structures, including the plasma membrane and any external encapsulating structures such as the cell wall and cell envelope.

negative regulation of cell organization and biogenesis

negative regulation of cell organisation and biogenesis

Any process that stops, prevents or reduces the rate of the processes involved in the assembly and arrangement of cell structures, including the plasma membrane and any external encapsulating structures such as the cell wall and cell envelope.

Catalysis of the reaction: L-serine + pyruvate = 3-hydroxypyruvate + L-alanine.
