Methionine transfer RNAs from the extreme halophile, Halobacterium cutirubrum

1.1. Formylation of methionyl-tRNA could not be demonstrated in Halobacterium cutirubrum, either in vitro or in vivo.2.2. Chromatography of [14C]methionyl-tRNAMet on BD-cellulose columns resolved two peaks.3.3. One of these chromatographically distinct species was capable of being formylated by the Escherichia coli methionyl-tRNA transformylase.
