This compilation presents in a small space the tRNA sequences so far published. The numbering of tRNAPhe from yeast is used following the rules proposed by the participants of the Cold Spring Harbor Meeting on tRNA 1978 (1,2;Fig. 1). This numbering allows comparisons with the three dimensional structure of tRNAPhe. The secondary structure of tRNAs is… (More)
The extracellular loop of P2X channel proteins contains a sequence stretch (positions 170-330) that exhibits similarities with the catalytic domains of class II aminoacyl-tRNA synthetases as shown by secondary structure predictions and sequence alignments. The arrangement of several conserved cysteines (positions 110-170) shows similarities with metal… (More)
By a stepwise synthesis strategy biofunctionalized Pyrrolopyrrole Cyanines (PPCy) with an asymmetric substitution pattern were obtained. These exhibit extremely strong and narrowband NIR absorption and fluorescence. Internalization of a peptide bound PPCy is demonstrated using live cell microscopy.
