Many key cell processes require prior cell uptake of amino acids from the environment,
which is facilitated by cell membrane amino acid transporters such as those of the L-type …

The mitochondrial carnitine/acylcarnitine carrier catalyzes the transport of carnitine and
acylcarnitines by antiport as well as by uniport with a rate slower than the rate of antiport …

The sodium-dependent citrate transporter of Klebsiella pneumoniae (Kp CitS) belongs to the
2-hydroxycarboxylate transporter (2-HCT) family and allows the cell to use citrate as sole …

ETT (originally designated as OCTN1; human gene symbol SLC22A4) and CTT (OCTN2;
SLC22A5) are highly specific transporters of ergothioneine and carnitine, respectively …

The structure and function of a cadaverine–lysine antiporter CadB and a putrescine–
ornithine antiporter PotE in Escherichia coli were evaluated using model structures based …

Acetate is found ubiquitously in the natural environment and can be used as an exogenous
carbon source by bacteria, fungi, and mammalian cells. A representative member of the …

The SLC25A20 transporter, also known as carnitine acyl-carnitine carrier (CAC), catalyzes
the transport of short, medium and long carbon chain acyl-carnitines across the …

The scavenging of host-derived sialic acid is important for a number of human pathogens
during colonization of mammalian mucous membranes (Severi et al., 2007). This has been …

The plasma membrane transporter ASCT2 is a well-known Na+-dependent obligatory
antiporter of neutral amino acids. The crucial role of the residue C467 in the recognition and …

L-lactate is an important metabolite, energy source, and signaling molecule in health and
disease. In mammals, its transport across biological membranes is mediated by …
