General description

1-Thioglycerol stimulates the synthesis of porphyrin in aerobically growing Escherichia coli. It is an inhibitor of glycerol kinase activity in vitro and in situ.

Application

It has been used in a study to assess thiol-sensitive genes and promoters of Escherichia coli.

Preparation Note

This product is miscible in ethanol (1 ml/ml, 50%, v/v), yielding a clear, colorless solution. It is also miscible in water (0.1 M).

The effect of 1-thioglycerol on the expression of genes of Escherichia coli was investigated. Pulse-labeled proteins from aerobically growing, 1-thioglycerol-treated E. coli were separated by two-dimensional gel electrophoresis, and their radioactivities were compared with those of identical proteins from nontreated

Hydrophilic/hydrophobic patterning is a powerful strategy to control folding in non-natural polymers/oligomers. In this contribution, we present a novel strategy for the preparation of alternating hydrophilic/hydrophobic patterned non-natural peptide foldamers. This strategy relies on the post-modification of a reactive peptide
