Studies on the Lactose Transport System in Escherichia coli
I should like to discuss very briefly the current status of studies in our laboratory of the membrane protein component of the lactose transport system of Escherichia coll. Previous publications (I, 2) have presented evidence that this protein, which can be selectively labeled with radioactive N-ethylmaleimide, is the product of the y gene of the lac operon, the long-sought permease protein. Th...
متن کاملEnergy coupling in the lactose transport system of Escherichia coli.
A mutant (ML 308-22) was isolated from Escherichia coli ML 308, which had lost the normal capacity to accumulate lactose analogs despite an increase in the membrane carrier activity. The exit of thiomethylgalactoside was much faster than normal, accounting for the inability of the cell to maintain high intracellular concentrations of galactosides. Growth of the mutant on lactose was normal at h...
متن کاملStandardization of different levels of lactose hydrolysis in the preparation of lactose hydrolyzed yoghurt
Yoghurt is a unique fermented dairy product, consumed throughout the world and the trend ofconsumption is increasing due to its unique health benefits. Yoghurt mix is often supplemented with MSNF(milk solids-non-fat), it may contain as much as 5.7% unhydrolysed lactose. Lactose can be hydrolysed withan enzyme lactase. Deficiency of lactase in lactose-intolerant persons leads to gastrointestinal...
متن کاملRegulation of lactose transport in Kluyveromyces lactis
Kluyveromyces lactis is able to ferment lactose and it is considered as an alternative model for biochemical, physiological and genetic studies in nonSaccharomyces yeasts. Understanding the mechanisms of lactose uptake and the regulation involved in the transport is an important step towards better biotechnological applications. The transport of lactose in K. lactis is mediated by a membrane pe...
متن کاملFrom 'lactose intolerance' to 'lactose nutrition'.
The concept of lactose intolerance has become embedded in Western medicine and developing economy medicine. It is based on evidence that intestinal lactase activity persists into later childhood and throughout life in only a minority of the world's population, notably northern European-derived populations. These people have the T single nucleotide polymorphism (SNP) of the rs49882359 allele (C/...
