The chemical reactions involving glyoxylate, the anion of glyoxylic acid, HOC-COOH.

The chemical reactions involving phosphatidylinositol, any glycophospholipid with its sn-glycerol 3-phosphate residue is esterified to the 1-hydroxyl group of 1D-myo-inositol.

The initial step in the formation of an actin filament, in which actin monomers combine to form a new filament. Nucleation is slow relative to the subsequent addition of more monomers to extend the filament.

The formation from simpler components of phosphoinositides, any of a class of glycerophospholipids in which the phosphatidyl group is esterified to the hydroxyl group of inositol.

Any complex that includes a dimer of molecules from the kinesin superfamily, a group of related proteins that contain an extended region of predicted alpha-helical coiled coil in the main chain that likely produces dimerization. The native complexes of several kinesin family members have also been shown to contain additional peptides, often designated light chains as all of the noncatalytic subunits that are currently known are smaller than the chain that contains the motor unit. Kinesin complexes generally possess a force-generating enzymatic activity, or motor, which converts the free energy of the gamma phosphate bond of ATP into mechanical work.

major histocompatibility complex class II receptor

A major histocompatibility complex class II receptor. These display processed antigens from virally-infected or transformed cells. Class-II-positive cells ('antigen-presenting cells') can take up antigens from outside by endocytosis, degrade them into small peptides, and re-export the peptides (now bound to MHC class II protein) to the cell surface. These peptide-MHC class II complexes can then be recognized by specific CD4+ lymphocytes.

negative regulation of transcription by carbon catabolites

Any process involving carbon catabolites that stops, prevents or reduces the rate of transcription. Carbon catabolite repression is a mechanism of genetic regulation in bacteria in which the accumulation of catabolites of one substance in the cell represses the formation of enzymes that contribute to the catabolism of other substances.
