Metal ions‐ and pH‐induced conformational changes of acutolysin A from Agkistrodon acutus venom probed by fluorescent spectroscopy

Abstract: Acutolysin A isolated from the venom of Agkistrodon acutus is a protein of 22 kDa with marked haemorrhagic and proteolytic activities. The metal ions‐ and pH‐induced conformational changes of acutolysin A have been studied by following fluorescence and activity measurements. Here, we provide evidence for the fact that native holo‐acutolysin A adopts two subtly different conformations, native state a (Na) stable in the weak acidic pH range from 6.0 to 7.0 with low activity and native state b (Nb) stable in the … Show more
