Engineering protein stability and specificity using fluorous amino acids: the importance of packing effects.

15 Nov 2009 The incorporation of extensively fluorinated, or fluorous, analogues of hydrophobic amino acids into proteins potentially provides the opportunity to modulate the physicochemical properties of proteins in a predictable manner. On the basis of the ... Read more...

Role of microRNA-155 at early stages of hepatocarcinogenesis induced by choline-deficient and amino acid-defined diet in C57BL/6 mice.

29 Sep 2009 MicroRNAs (miRs) are conserved, small (20-25 nucleotide) noncoding RNAs that negatively regulate expression of messenger RNAs (mRNAs) at the posttranscriptional level. Aberrant expression of certain microRNAs plays a causal role in tumorigenesis. ... Read more...

D-amino acids govern stationary phase cell wall remodeling in bacteria.

16 Sep 2009 In all known organisms, amino acids are predominantly thought to be synthesized and used as their L-enantiomers. Here, we found that bacteria produce diverse D-amino acids as well, which accumulate at millimolar concentrations in supernatants of ... Read more...
