Abstract
Escherichia coli penicillin-binding proteins (PBPs) were associated only with inner membrane vesicles when separated on 30 to 65% or 19 to 49% (wt/wt) sucrose gradients. Fractionation of vesicles through the low-density gradient revealed at least two classes of PBP-inner membrane associations. The first class consisted of PBPs 1 through 4, and the second class consisted of PBPs 5 through 8. These classes were distinguished by the density of vesicles with which they were associated; class 1 PBPs migrated with vesicles of higher density than did class 2 PBPs. Such combinations suggest that PBPs are nonrandomly distributed within the inner membrane, implying potential functional relationships among the PBPs themselves and with particular membrane domains. In addition, in cell lysates and in vesicle fractions, a 60,000-dalton aztreonam-insensitive PBP or protein fragment was observed which could potentially be confused with PBP3.
