2.3.1.54 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 675371 2.3.1.54 stable for 2 h at 35°C in untreated cell-free extracts under strictly anaerobic conditions. In dialyzed cell-free extracts, activity decreases gradually. 663000 2.3.1.54 unstable even when stored anaerobically 487222 2.3.1.54 virtually stable at 0°C and pH 8.0 if kept in media which display a redoxpotential of 0.2 V or below 487221
