Galactose-specific asialoglycoprotein receptor is involved in lipoprotein (a) catabolism.
Lp(a) [lipoprotein (a)] is a highly atherogenic plasma lipoprotein assembled from low-density lipoprotein and the glycoprotein apolipoprotein (a). The rate of Lp(a) biosynthesis correlates significantly with plasma Lp(a) concentrations, whereas the fractional catabolic rate does not have much influence. So far, little is known about Lp(a) catabolism. To study the site and mode of Lp(a) cataboli...
متن کاملPathways for lactose/galactose catabolism by Streptococcus salivarius.
Galactokinase and beta-galactosidase-deficient strains of Streptococcus salivarius were constructed to define the pathways for lactose and galactose catabolism. It was found that S. salivarius does not possess a lactose-specific phosphoenolpyruvate phosphotransferase system (PTS), that intracellular lactose was hydrolyzed by beta-galactosidase, and that galactose is catabolized exclusively thro...
متن کاملPneumococcal galactose catabolism is controlled by multiple regulators acting on pyruvate formate lyase
Catabolism of galactose by Streptococcus pneumoniae alters the microbe's metabolism from homolactic to mixed acid fermentation, and this shift is linked to the microbe's virulence. However, the genetic basis of this switch is unknown. Pyruvate formate lyase (PFL) is a crucial enzyme for mixed acid fermentation. Functional PFL requires the activities of two enzymes: pyruvate formate lyase activa...
متن کاملCarbohydrate catabolism and the enhancement of uptake of galactose in hamster cells transformed by polyoma virus.
Untransformed as well as polyoma virus-transformed hamster cells can be grown equally well on a slow catabolite like galactose as on a rapid catabolite like glucose. The rate of uptake of galactose is greatly enhanced in the transformed cells as compared with untransformed cells, and this enhancement of entry was as markedly expressed in galactose-grown cultures as in glucose-grown cultures. Si...
متن کاملLactose and D-galactose catabolism in the filamentous fungus Aspergillus nidulans.
The disaccharide lactose is a byproduct of cheese production accumulating to amounts of 800,000 tons per year worldwide, of which 15% is used as a carbon source for various microbial fermentations. Nevertheless, little is known about the regulation of its metabolism in filamentous fungi. Lactose is metabolized slowly, and some important fungi such as A. niger cannot use it at all. A more detail...
