'''Stringent starvation protein''' A (SspA) is an RNA polymerase-associated protein involved in nucleotide metabolism acid tolerance and virulence of bacteria<ref>PMID:32785630</ref>.
'''Stringent starvation protein''' A (SspA) is an RNA polymerase-associated protein involved in nucleotide metabolism, acid tolerance and virulence of bacteria<ref>PMID:32785630</ref>.
In ''Francisella'' virulence, a set of regulators are essensial for its activation.  These regulators include the heterodimer of SspA, macrophage growth locus A (MglA) and pathogenicity island gene regulator (PigR).  The guanosine-tetraphosphate (ppGpp) is also involved in coordinating the virulence. '''Stringent starvation protein B''' (SspB) binds to residues in the tag of tmRNA proteins marking them for degradation <ref>PMID:11535833</ref>.
