Resuscitation promoting factors: a family of microbial proteins in survival and resuscitation of dormant mycobacteria.

ABSTRACT: Mycobacterium tuberculosis, the causative agent of tuberculosis (TB), is an extraordinarily successful pathogen of humankind. It has been estimated that up to one-third of the world's population is infected with M. tuberculosis, and this population is an important reservoir for disease reactivation. Resuscitation promoting factor (Rpf) is a secretory protein, which was first reported in Micrococcus luteus. There are five functionally redundant Rpf-like proteins found in M. tuberculosis. Rpf promotes the resuscitation of dormant bacilli to yield normal, viable colony forming bacteria. All Rpfs share a conserved domain of about 70 amino acids and possess a lysozyme-like activity. The structural studies of the conserved domain suggest that Rpfs could be considered as a c-type lysozyme and lyt
