Bacterial Amino Acid Transport Systems
The roles of the cell membrane as both a permeability barrier to foreign substances and as a selective filter which admits nutrient molecules have been recognized as fundamentally important to animal physiology since the first decade of this century. It was not until the 1950's, however, that microbiologists recognized that bacteria possess membrane transport systems, distinct from their metabo...
متن کاملMammary-tissue amino acid transport systems.
Amino acid movement across cell membranes is mediated by a variety of transport systems. These pathways have been extensively studied and characterized in a large array of cell types and include both Na+-dependent and Naf-independent carriers. In addition, recent work suggests that channels may also play a role in amino acid transport. The objective of the present paper is to review current kno...
متن کاملPlacental amino acid transport.
Normal fetal growth and development depend on a continuous supply of amino acids from the mother to the fetus. The placenta is responsible for the transfer of amino acids between the two circulations. The human placenta is hemomonochorial, meaning that the maternal and fetal circulations are separated by a single layer of polarized epithelium called the syncytiotrophoblast, which is in direct c...

متن کاملPolarized Amino Acid Transport
The transport of three neutral amino acid analogs has been studied in an epithelial cell line from a pig kidney. 2-Aminoisobutyric acid is accumulated by U C PKI cells against a concentration gradient through a mechanism with several features of a carrier-mediated process. The influx is accounted for by a saturable Na+dependent and nonsaturable Na+-independent process. The total influx of 2-(me...
