2.4-A resolution structure of Bacillus subtilis SppA catalytic domain reveals eight SppA molecules in the asymmetric unit, forming a dome-shaped octameric complex. Residue Ser147 may serve as the nucleophile and Lys199 may serve as the general base. The SppA S1 substrate specificity pocket is deep, narrow and hydrophobic, but with a polar bottom. The S3 pocket, which is constructed from two neighboring proteins, is shallower, wider and more polar than the S1 pocket | Bacillus subtilis |
