Abstract
Lysyl-transfer ribonucleic acid (tRNA) species from a spore-forming strain of Bacillus subtilis (168 trp2−) and an early blocked asporogenous mutant (spoA 12) were compared on reversed-phase and methylated albumin-kieselguhr columns. Lysyl-tRNA species from spores and the asporogenous mutant in stationary phase both exhibited altered chromatographic profiles compared to that of log-phase cells. The major peak in spore lysyl-tRNA species eluted later than that characteristic of vegetative cells, whereas the major peak of the lysyl-tRNA species from the asporogenous mutant in stationary phase eluted earlier. Although the early eluting lysyl-tRNA species was observable on methylated albumin columns, the late eluting peak was not detectable by that column technique. By using a shallower gradient on an RPC-2 column, the resolution of all lysyl-tRNA species increased. Several subspecies were revealed. The chromatographic comparisons clearly show that both the spore-forming strain and the asporogenous mutant undergo relative increases in different lysyl-tRNA species when grown to late stationary phase. No new species seem to be involved but rather altered amounts of minor species existing in log-phase cells. The experiments also demonstrate the usefulness of reversed-phase columns for such comparisons.
