The process whereby a relatively unspecialized hemopoietic stem cell acquires the specialized features of a B cell.

Catalysis of the reaction: octane + reduced rubredoxin + O2 = 1-octanol + oxidized rubredoxin + H2O.

Catalysis of the reaction: UDP-N-acetyl-D-glucosamine + alpha-D-mannosyl-1,6-(N-acetyl-beta-D-glucosaminyl-1,2-alpha-D-mannosyl-1,3)-beta-D-mannosyl-R = UDP + N-acetyl-beta-D-glucosaminyl-1,2-alpha-D-mannosyl-1,6-(N-acetyl-beta-D-glucosaminyl-1,2-alpha-D-mannosyl-1,3)-beta-D-mannosyl-R.

Catalysis of the hydrolysis of terminal non-reducing N-acetyl-D-galactosamine residues in N-acetyl-alpha-D-galactosaminides.

The chemical reactions involving melatonin (N-acetyl-5-methoxytryptamine).

The formation from simpler components of melatonin (N-acetyl-5-methoxytryptamine).

Catalysis of the reaction: octanoyl-CoA + L-carnitine = CoA + L-octanoylcarnitine.

The 'de novo' formation of a microtubule, in which tubulin heterodimers form metastable oligomeric aggregates, some of which go on to support formation of a complete microtubule. Microtubule nucleation usually occurs from a specific site within a cell.

Modulates the activity of a molecular chaperone.

Catalysis of the reaction: 3'-phosphoadenosine 5'-phosphosulfate (PAPS) + chondroitin = adenosine 3',5'-bisphosphate + chondroitin 6'-sulfate.

Folding of the microtubule constituent proteins alpha- and beta-tubulin into the native alpha-beta heterodimer.

Increases the activity of a molecular chaperone.

Partial folding of alpha- or beta-tubulin into a non-native folding intermediate, mediated by cytosolic chaperonin CCT.

Completion of folding of alpha- and beta-tubulin; takes place subsequent to chaperonin-mediated partial folding; mediated by a complex of folding cofactors.

Folding of the microtubule constituent protein beta-tubulin.

negative regulation of microtubule depolymerization

Any process that stops, prevents or reduces the rate of microtubule polymerization; prevention of depolymerization of a microtubule can result from binding by 'capping' at the plus end (e.g. by interaction with another cellular protein of structure) or by exposing microtubules to a stabilizing drug such as taxol.
