Characterization of extracellular RNases of host dependent Bdellovibrio bacteriovorus 109 D

Creator:: Hazen, Ronald Eugene
Abstract:: The growth of bdellovibrios at the expense of the host organism involves the catabolism of host cell macromolecular components and the subsequent anabolistic incorporation into bdellovibrio progeny. Extracellular enzymes specific for the various substrates provided by the host cell are present. In this study the extracellular RNase of Bdellovibrio bacteriovorus...
