  • Title: Protein Targeting during Bacillus subtilis Sporulation.
    Author: Dworkin J.
    Journal: Microbiol Spectr; 2014 Feb; 2(1):TBS-0006-2012. PubMed ID: 26082125.
    Abstract:
    The Gram-positive bacterium Bacillus subtilis initiates the formation of an endospore in response to conditions of nutrient limitation. The morphological differentiation that spores undergo initiates with the formation of an asymmetric septum near to one pole of the cell, forming a smaller compartment, the forespore, and a larger compartment, the mother cell. This process continues with the complex morphogenesis of the spore as governed by an intricate series of interactions between forespore and mother cell proteins across the inner and outer forespore membranes. Given that these interactions occur at a particular place in the cell, a critical question is how the proteins involved in these processes get properly targeted, and we discuss recent progress in identifying mechanisms responsible for this targeting.
