Transport systems for neutral amino acids in the pigeon erythrocyte.
Uptake and inhibition studies show that the uptake of neutral amino acids by the pigeon red blood cell is divided among four systems: a Naf-independent, nonexchanging system operative for amino acids with large hydrocarbon side chains; a Na+-dependent, exchanging system (ASCP) for alanine, serine, cysteine, proline, and probably also threonine and similar amino acids, very similar to systems se...
متن کاملRenal transport of neutral amino acids
Uptake of L-proline, hydroxy-L-proline and 5-oxo-L-proline by luminal-membrane vesicles isolated either from whole cortex or from pars convoluta or pars recta of proximal tubules was studied by a spectrophotometric method. Uptake of L-proline and hydroxy-L-proline by vesicles from whole cortex was mediated by both Na+dependent and Na+-independent, but electrogenic, processes, whereas transport ...
متن کاملThe transport of neutral amino acids in cultured human fibroblasts.
The transport of neutral amino acids and their interactions for uptake have been studied in skin-derived-diploid human fibroblasts cultured at confluency. Properly timed preincubations in a medium defined in composition and requirements have been adopted to control size of internal amino acid pools and regulatory interferences affecting amino acid transport. L-Proline, L-alanine, and L-leucine ...

Physiol. 2 17 (4) : 974-980. 1969.-CSF clearances of L-leucine, cycloleucine, I;-alanine, and AIB were measured during ventriculocisternal perfusions of 14Clabeled amino acids in cats. Amino acid clearances exceeded that of 12”1-labeled human seru...
متن کاملNeutral amino acid transport systems in Chinese hamster ovary cells.
The neutral amino acid transport systems A, ASC, and L have been characterized in the Chinese hamster ovary cell. System A, defined by its sodium ion dependency and inhibition by 2-methylaminoisobutyric acid, was found to be extremely sensitive to the pH of the external medium and to increase in response to starvation for amino acids. System ASC, identified by its sodium ion dependency and into...
