Evaluation of a novel 16S rRNA/tRNAVal mitochondrial marker for the identification and phylogenetic analysis of shrimp species belonging to the superfamily Penaeoidea.

16 May 2009 In this study, we infer the phylogenetic relationships within commercial shrimp using sequence data from a novel mitochondrial marker consisting of an approximately 530-bp region of the 16S ribosomal RNA (rRNA)/transfer RNA (tRNA)(Val) genes ... Read more...

The yfiC gene of E. coli encodes an adenine-N6 methyltransferase that specifically modifies A37 of tRNA1Val(cmo5UAC).

19 Apr 2009 Transfer RNA is highly modified. Nucleotide 37 of the anticodon loop is represented by various modified nucleotides. In Escherichia coli, the valine-specific tRNA (cmo(5)UAC) contains a unique modification, N(6)-methyladenosine, at position 37; ... Read more...

Bases in the anticodon loop of tRNA(Ala)(GGC) prevent misreading.

20 Mar 2009 The bases at positions 32 and 38 in the tRNA anticodon loop are known to have a specific conservation depending upon the anticodon triplets. Here we report that evolutionarily conserved pairs of bases at positions 32 and 38 in tRNA(Ala)(GGC) prevent ... Read more...
