Methyl b-D-thiogalactopyranoside

甲基-β-D-硫代半乳糖苷,

Methyl b-D-thiogalactopyranoside (MTGP) is a cell lysis agent that can be used for diagnostic purposes to measure enzyme activities in cells. It is also used to determine the kinetic of an enzyme reaction, as well as its acid formation. MTGP has been shown to inhibit sugar transport and metabolism by binding to the sugar molecule and preventing it from passing through cellular membranes. This inhibition prevents the accumulation of proton gradients across the membrane, which disrupts ATP production and leads to cell death. MTGP is also an inhibitor of glucose-6-phosphate dehydrogenase (G6PDH), which converts glucose into sorbitol. Sorbitol accumulates intracellularly and leads to cell death by osmotic lysis.
