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

Catalysis of the transfer of an amino group from L-tyrosine to an acceptor, usually a 2-oxo acid.

Catalysis of the reaction: E1 + ubiquitin + ATP--> E1-ubiquitin + AMP + PPi, where the E1-ubiquitin linkage is a thioester bond between the C-terminal glycine of Ub and a sulfhydryl side group of an E1 cysteine residue. This is the first step in a cascade of reactions in which ubiquitin is ultimately added to a protein substrate.

Any process that modulates the frequency, rate or extent of entry of bacterium into host cell.

Any process in which an organism modulates the frequency, rate or extent to which it enters into the host organism, where the two organisms are in a symbiotic interaction.

Any process that stops, prevents or reduces the frequency, rate or extent of entry of bacterium into host cell.

Any process that stops, prevents or reduces the frequency, rate or extent of renal albumin absorption.

Any process that activates or increases the frequency, rate or extent of renal albumin absorption.

Any process that activates or increases the frequency, rate or extent of B cell chemotaxis.

Any process that stops, prevents or reduces the frequency, rate or extent of RNA polymerase I regulatory region sequence-specific DNA binding.

Any process that modulates the frequency, rate or extent of high voltage-gated calcium channel activity.

Any process that stops, prevents or reduces the frequency, rate or extent of high voltage-gated calcium channel activity.

Any process that activates or increases the frequency, rate or extent of high voltage-gated calcium channel activity.

Any process that modulates the frequency, rate or extent of cell communication by electrical coupling involved in cardiac conduction.

Any process that stops, prevents or reduces the frequency, rate or extent of cell communication by electrical coupling involved in cardiac conduction.

Any process that activates or increases the frequency, rate or extent of cell communication by electrical coupling involved in cardiac conduction.

Catalysis of the transfer of ubiquitin from one protein to another via the reaction X-Ub + Y --> Y-Ub + X, where both X-Ub and Y-Ub are covalent linkages.
