An isolated amino acid transporter polypeptide comprising (i) the amino acid sequence of SEQ ID NO:2 or SEQ ID NO:4 or (ii) a variant of (i) which has amino acid transporter activity or (iii) a fragment of (i) or (ii) which has amino acid transporter activity. The polypet...
With the assumption that individual amino acids are independently distributed into naturally occurring polypeptide chains, it is shown that amino acid pairs with 0–2 arbitrary intervening residues are also independently distributed, with a few possible exceptions. This is not true of N- and C-termin...
The emergence of robust methods to expand the genetic code allows incorporation of non-canonical amino acids into the polypeptide chain of proteins, thus making it possible to introduce unnatural chemical functionalities in enzymes. In this Perspective, we show how this powerful methodology is used to...
Long chain carbon and cyclic amino acid flexizyme charging To gain insights about possible constraints for using Fx to charge long chain carbon amino acid substrates onto tRNAs, 10 substrates (1–5in Fig.2aand2i–2vin the characterization section inSupplementary Information) were examined with incr...

Amino acid chains, called polypeptides, are the building blocks needed in drug development and the creation of new biomaterials. Traditionally, making polypeptide chains has been a very complicated process. Synthesizing and purifying the NCAs requires days of tedious effort, and building the polypeptide...
A large proportion of CCM-supplied amino acids are diverted to these non-proteogenic pathways that in turn could influence the fate of cells in culture (Fig. 2) (Consortium U 2008). Fig. 2 Cellular fate of amino acids in cell culture. a Comparison of the amino acid composition of the ...
The a-amino acids in peptides and proteins (excluding proline) consist of a carboxylic acid (-COOH ) and an amino (-NH 2) functional group attached to the same tetrahedral carbon atom. This carbon is the a-carbon. Distinct R-groups, that distinguish one amino acid from another, also ...
