ABSTRACT
PS1 is a major exported protein of Corynebacterium glutamicum homologous to mycobacterial antigen 85. It is largely associated with the mycolic acid-containing cell wall and acts as a mycoloyl transferase. The transport of PS1 to the cell wall is slow and occurs through two energetically distinct steps:
the first one, which includes processing by signal peptidase, is rapid and inhibited by sodium azide or carbonyl cyanide m-chlorophenylhydrazone. This step is probably associated with translocation across the cytoplasmic membrane. The kinetics of the second step depend on the size of the polypeptide chain to be transported but neither ATP nor proton motive force is required. This step may correspond to the diffusion of PS1 across the cell wall to its final location.
