Abstract
Virion-associated peptidoglycan hydrolases have a potential as antimicrobial agents due to their ability to lyse Gram positive bacteria on contact. Fusion proteins HydH5SH3b and HydH5Lyso comprising full-length peptidoglycan hydrolase HydH5 from thebacteriophage vB_SauS-phi-IPLA88 in combination with the SH3b cell wall-binding domain from lysostaphin or full length lysostaphin, respectively, exhibited high lytic activity against livecells. CHAPSH3b, a HydH5 CHAP (cysteine, histidine-dependent amidohydrolase/peptidase) domain from truncated HydH5 in combination with the SH3b domain of lysostaphin, exhibited the highest lytic activity against livecells. HydH5 and its derivative fusions lysed bovine and human, methicillin-resistant(MRSA) N315 strain, and humanstrains in zymogram, plate lysis and turbidity reduction assays. HydH5 and its derivative fusions displayed antimicrobial synergy with the endolysin LysH5 (also encoded by vB_SauS-phi-IPLA88) in vitro suggesting the two enzymes have distinct cut sites and thus may be more efficient in combination for elimination of staphylococcal infections.
