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.

negative regulation of transcription by glucose

Any process involving glucose that stops, prevents or reduces the rate of transcription. The presence of glucose in the growth medium inhibits the synthesis of certain enzymes in bacteria growing on the medium. For example, transcription of some catabolic operons is under negative control by specific repressors and glucose is an anti-inducer of xylose utilization and glycerol kinase.

Any of the long, generally straight, hollow tubes of internal diameter 12-15 nm and external diameter 24 nm found in a wide variety of eukaryotic cells; each consists (usually) of 13 protofilaments of polymeric tubulin, staggered in such a manner that the tubulin monomers are arranged in a helical pattern on the microtubular surface, and with the alpha/beta axes of the tubulin subunits parallel to the long axis of the tubule; exist in equilibrium with pool of tubulin monomers and can be rapidly assembled or disassembled in response to physiological stimuli; concerned with force generation, e.g. in the spindle.

Catalysis of the reaction: N,N-dimethylglycine + acceptor + H2O = sarcosine + formaldehyde + reduced acceptor.

Any multimeric complex connected to a microtubule.

Any microtubule that is part of a mitotic or meiotic spindle; anchored at one spindle pole.

The formation from simpler components of glycerolipids, any lipid with a glycerol backbone.

The chemical reactions involving phosphatidylcholines, any of a class of glycerophospholipids in which the phosphatidyl group is esterified to the hydroxyl group of choline. They are important constituents of cell membranes.
