Rescue of ribosomal protein bL27 in Streptococcus pneumoniae TIGR4 by an alternate protease
These results suggested the presence of an alternate bL27-processing protease in TIGR4 that was absent from D39, and shed light on an alternative mechanism for bL27 maturation, and indicate that some strains of S. pneumoniae harbor horizontally acquired redundant pathways for this essential ribosome processing step.
