After purification from extracts of whole cells, M1 RNA, the catalytic subunit of
ribonuclease P
from Escherichia coli, apparently must undergo a change in conformation before it can function catalytically. The rate of this conformational change is dependent upon the duration of incubation at various temperatures and pH.
delta E
of the transition at pH 7.5 is approximately 36 kcal/mol. The change in conformation is not sensitive to Mg2+ concentration between 10 and 100 mM. A decrease in A260 of M1 RNA in solution has been observed during the incubation period that potentiates the conformational change at 30 degrees C, but no direct correlation can yet be made to specific structural rearrangements.
