PFL2 appears to be stabilized by several factors including an increased number of ion pairs, differences in buried charges, a truncated N terminus, anchoring of loops and N terminus via salt-bridges,changes in the oligomeric interface and perhaps also the higher oligomerization state of the protein
stable for 2 h at 35Â°C in untreated cell-free extracts under strictly anaerobic conditions. In dialyzed cell-free extracts, activity decreases gradually.
unstable even when stored anaerobically
virtually stable at 0Â°C and pH 8.0 if kept in media which display a redoxpotential of 0.2 V or below
