Sequence analysis, SDS-PAGE and zymogram of the 6 × His tagged full-length HydH5 and deletion constructs. A) Pfam domain organization of HydH5 and its deletion constructs containing CHAP (cysteine, histidine-dependent amidohydrolases/peptidases) and LYZ2 (lysozyme subfamily 2) domains. Numbers indicate the amino acid positions in HydH5. B) Comassie-blue stained SDS-PAGE gel of lane 1: purified HydH5 (76.7 kDa), lane 2: purified CHAP domain (17.2 kDa), lane 3: purified LYZ2 domain (21.1 kDa); and zymogram analysis of lane 4: purified HydH5, lane 5: crude cell extracts of induced E. coli clones containing CHAP domain, lane 6: crude cell extracts of induced E. coli clones containing LYZ2 domain. Zymograms were run with S. aureus Sa9 cells embedded in the gel. Molecular mass standards (Prestained SDS-PAGE Standards, broad range, BioRad Laboratories) are indicated on the left.
