LasA and LasD are staphylolytic proteinases which are secreted by the
opportunistic pathogen Pseudomonos aeruginosa. We have previously desc
ribed the purification and characterization of both LasA and LasD, a 2
1-kDa protein which shares many of the enzymatic properties of LasA In
this follow-up study we describe the isolation of the 42-kDa precurso
r of LasA (proLasA) and demonstrate the ability of the purified LasD p
roteinase to cleave the inactive proLasA to the 20-kDa active form of
the proteinase. (C) 1998 Academic Press.
