Descrizione generale

The uptake of methyl-β-D-thiogalactoside (TMG), lactose, and glucose is maintained by the phosphoenolpyruvate-dependent phosphotransferase system.

Applicazioni

Methyl-β-D-thiogalactoside has been used in a study to analyze inducers of the E.coli lac repressor system. It has also been used in a study that investigated the utilization of lactose by Streptococcus faecalis.

Confezionamento

Bottomless glass bottle. Contents are inside inserted fused cone.

Anionic O2 derivatives of methyl 3-deoxy-3-(4-methylbenzamido)-1-thio-beta-D-galactopyranoside have been synthesized as inhibitors against galectin-3. The sulfate, H-phosphonate, and benzyl phosphate derivatives showed an increased affinity as compared to the parent unsubstituted galactopyranoside. Modeling revealed arginine-144 being pinched by the C3 benzamide

Although the inducible prokaryotic lac repressor system has been successfully adapted for control of gene expression in mammalian cells, little information is available on the pharmacokinetics of beta-galactoside inducers in mammalian cells for optimizing this system. These studies directly measure

The CpxA-CpxR two-component signal transduction pathway of Escherichia coli was studied in a mutant (pss-93) lacking phosphatidylethanolamine (PE). Several properties of this mutant are comparable to phenotypes of cpxA point mutants, indicating that this two-component pathway is activated in PE-deficient

Most commonly used expression systems in bacteria are based on the Escherichia coli lac promoter. Furthermore, lac operon elements are used today in systems and synthetic biology. In the majority of the cases the gratuitous inducers IPTG or TMG are
