Interaction between membrane curvature sensitive factors SpoVM and SpoIVA in Bicelle condition

SpoVM and SpoIVA are essential proteins for coat assembly in Bacillus subtilis. SpoVM is a membrane curvature sensor, specifically localized on the forespore membrane. SpoIVA is an ATP hydrolase that self-assembles by hydrolyzing ATP. In this work, SpoVM and its mutant SpoVM were obtained by cyanoge...

Description
Summary:SpoVM and SpoIVA are essential proteins for coat assembly in Bacillus subtilis. SpoVM is a membrane curvature sensor, specifically localized on the forespore membrane. SpoIVA is an ATP hydrolase that self-assembles by hydrolyzing ATP. In this work, SpoVM and its mutant SpoVM were obtained by cyanogen bromide cleavage and reconstituted into bicelles. The purification of SpoIVA was achieved through a rigorous process involving Ni-NTA chromatography column and size exclusion chromatography. This study utilized Biacore to obtain a direct determination of the kinetic parameters of interaction between SpoVM (SpoVM ) and SpoIVA in Bicelle conditions.
