Cellular distribution of neutral and basic amino acid transport systems in rabbit ileal mucosa.
1. An autoradiographic technique is described whereby the cellular location of tritiated amino acids can be determined following uptake by rabbit ileal mucosa. 2. Stirring solutions in contact with the intestinal mucosa during measurement of rapid influx changes the quantity, but not the distribution, of alanine taken up by the tissue. 3.

1. The kinetic parameters of lysine and alanine uptake by rabbit ileal mucosa have been measured in the presence and absence of Na. 2. Using lysine as an inhibitor of part of alanine uptake in the absence of Na it has been possible to define two mediated systems for alanine entry.

Research Progress on Evaluation Method of Functional Characteristics of Food-Derived Peptides, Molecular Structure-Activity Relationship and Absorption and Metabolism Mechanism(食源性肽的功能特性评价方法、分子构效关系及吸收代谢机制) [PDF]
Peptides were compounds with intermediate molecular structures between amino acids and proteins, having numerous nutritional properties including easy absorption, low osmotic pressure, low immunogenicity, and high tissue permeability.

An 8-week feeding trial was conducted using the rice field eel (Monopterus albus) with six isonitrogenous and isoenergetic experimental diets of basic feed supplemented with different levels of methionine (0, 2, 4, 6, 8, or 10 g/kg).

Cysteine residues in the C-terminus of the neutral- and basic-amino-acid transporter heavy-chain subunit contribute to functional properties of the system b0,+-type amino acid transporter [PDF]
The neutral- and basic-amino-acid-transport glycoprotein NBAT (rBAT, D2) expressed in renal and jejunal brush-border membranes interacts with the b0,+AT permease to produce a heteromeric transporter effecting amino acid and cystine absorption. NBAT mutations result in type I cystinuria.

Evidence for Distinct Amino Acid Transport Systems in Cultured Tobacco Cells
It is shown by competition experiments that tobacco cell lines have distinct transport systems for ʟ-amino acids. For all tested amino acids the Lineweaver-Burk plots were diphasic indicating the presence of more than one carrier for any one amino acid ...

Mouse blastocysts which had been activated from diapause in utero appeared to take up amino acids via a Na+-dependent transport system with novel characteristics. In contrast to other cell types, uptake of 3-aminoendobicyclo [3,2,1]octane-3-carboxylic acid (BCO) by blastocysts was largely Na+ dependent. Moreover, L-alanine and BCO met standard criteria

Preimplantation mouse blastocysts were found to contain at least three mediated components of Na+-independent amino acid transport. The two less conspicuous components seemed to be selective for either cationic or zwitterionic substrates but were not characterized further or examined for multiple transport activities.

Basic amino acid transport in Escherichia coli.
The uptake of the basic amino acids lysine, ornithine, and arginine is mediated by three transport systems in Escherichia coli K-12 strain 7. Lysine uptake occurs by means of two kinetically distinct systems.
