Myxococcus xanthus protein C is a major spore surface protein.

abstract：:Bacteria possess multiple mechanisms to survive exposure to various chemical stresses and antimicrobial compounds. In the enteric bacterium Escherichia coli, three homologous transcription factors-MarA, SoxS, and Rob-play a central role in coordinating this response. Three separate systems are known to regulate the ex...
