Any process that results in a change in state or activity of a cell or an organism (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of a lead ion stimulus.

Any process that modulates the frequency, rate or extent of the chemical reactions and pathways involving urea.

Any process that modulates the frequency, rate or extent of nitrogen cycle metabolic process.

The chemical reactions and pathways resulting in the formation of the pectidic homogalacturonan, characterized by a backbone of (1->4)-linked alpha-D-GalpA residues that can be methyl-esterified at C-6 and carry acetyl groups on O-2 and O-3.

Catalysis of the reaction: 71-hydroxychlorophyll(ide) a + NAD(P)+ = chlorophyll(ide) b + NAD(P)H + H+.

The assembly from its constituent parts of a pilus, a short filamentous structure of bacterial cell, flagella-like in structure and generally present in many copies. Pili are variously involved in transfer of nucleic acids, adherence to surfaces, and formation of pellicles. Is required for bacterial conjugation, or can play a role in adherence to surfaces (when it is called a fimbrium), and in the formation of pellicles.

A process that is carried out at the cellular level which results in the assembly, arrangement of constituent parts, or disassembly of a pilus, a short filamentous structure on a bacterial cell, flagella-like in structure and generally present in many copies.

Any process that activates or increases the frequency, rate or extent of the chemical reactions and pathways resulting in the breakdown of amides.

Any process that modulates the frequency, rate or extent of the chemical reactions and pathways resulting in the breakdown of amides.

The chemical reactions and pathways resulting in the formation of GDP-mannose, a substance composed of mannose in glycosidic linkage with guanosine diphosphate.

Any process that modulates the frequency, rate or extent of the chemical reactions and pathways resulting in the breakdown of urea.

Any process that activates or increases the frequency, rate or extent of inner ear receptor cell differentiation.

Any process that activates or increases the frequency, rate or extent of mechanoreceptor differentiation.

Any process that modulates the frequency, rate or extent of inner ear receptor cell differentiation.

Catalysis of the reaction: lariciresinol + NADPH + H+ = secoisolariciresinol + NADP+.

Any process that modulates the frequency, rate or extent of ATP citrate synthase activity.

Any process that modulates the frequency, rate or extent of transferase activity, the catalysis of the transfer of a group, e.g. a methyl group, glycosyl group, acyl group, phosphorus-containing, or other groups, from one compound (generally regarded as the donor) to another compound (generally regarded as the acceptor). Transferase is the systematic name for any enzyme of EC class 2.

Catalysis of the reaction: 2-oxoglutarate + LL-2,6-diaminopimelate = (S)-2,3,4,5-tetrahydrodipicolinate + L-glutamate + H(2)O + H(+).

Any process that modulates the frequency, rate or extent of mechanoreceptor differentiation.
