Acidic and basic amino acid transport systems of Penicillium chrysogenum

Archives of Biochemistry and Biophysics, 1971
Abstract Penicillium chrysogenum possesses a relatively specific constitutive transport system for the basic amino acids l -lysine and l -arginine (Km = 6 × 10−6 m , Vmax = 1 μmole/g-min). This system has a low affinity for 2,4-diaminobutryate, l -ornithine, and l -histidine.

Multiple transport systems for basic amino acid transport in streptomyces hydrogenans

Biochimica et Biophysica Acta (BBA) - Biomembranes, 1973
Abstract In Streptomyces hydrogenans the uptake of basic amino acids occurs via several transport systems: 1. 1. One system (System bArg) is highly specific for arginine (Km = 7.10−6 M). l -Arginine influx is only inhibited by closely related analogs such as d -arginine, canavanine and arginine methyl ester, but not by lysine, ornithine ...

EVIDENCE FOR SEPARATE SYSTEMS FOR THE TRANSPORT OF NEUTRAL AND BASIC AMINO ACIDS ACROSS THE BLOOD‐BRAIN BARRIER

Journal of Neurochemistry, 1971
Abstract— The effects of high circulating concentrations of several amino acids on the free amino acids of rat brain were measured, to see whether or not the results followed any consistent pattern. High circulating concentrations of large, neutral amino acids (phenylalanine, valine or isoleucine) caused significantly decreased values only of other ...

Transport Behavior of Basic Amino Acids through an Organic Liquid Membrane System

Separation Science and Technology, 1994
Abstract The transport behavior of basic amino acids (BAA), such as arginine (Arg), histidine (His), and ornithine (Orn), through an organic liquid membrane system (LMS) was investigated. The LMS was composed of two aqueous phases (Phases I and II) separated by an organic phase of chloroform containing sodium di-(2-ethylhexyl) sulfosuccinate (Aerosol ...
