An archaeal aminoacyl-tRNA synthetase missing from genomic analysis

J Bacteriol. 1999 Sep;181(18):5880-4. doi: 10.1128/JB.181.18.5880-5884.1999.

Abstract

The complete genomic sequencing of Methanococcus jannaschii cannot identify the gene for the cysteine-specific member of aminoacyl-tRNA synthetases. However, we show here that enzyme activity is present in the cell lysate of M. jannaschii. The demonstration of this activity suggests a direct pathway for the synthesis of cysteinyl-tRNA(Cys) during protein synthesis.
