Comments |
In E. coli, s32 is synthesized at a basal level at all temperatures,
but its cellular concentration remains low as a
result of rapid proteolysis by FtsH, assisted by the DnaK
and GroESL chaperone systems, leading to a s32 halflife
of ~ 1 min (primary source). For half life of ~2min see PMID 18721134 p.4767 right column 2nd paragraph |
