Abstract
Rolf Stettler Claudia Thurner Dietmar Stax Leo Meile Thomas Leisinger Evidence for a defective prophage on the chromosome of Methanobacterium wolfei FEMS Microbiology Letters Volume 132 Issue 12 October 1995 Pages 85–89 https//doiorg/101111/j157469681995tb07815xEvidence shows the presence on the chromosome of Methanobacterium wolfei of a defective prophage which by DNADNA hybridization is closely related to the virulent archaeophage ψM1 of Methanobacterium thermoautotrophicum Marburg Partial sequencing of a M wolfei 16S rRNA gene and phylogenetic analysis indicated that this organism is more closely related to other representatives of the genus Methanobacterium than to M thermoautotrophicum Marburg The chromosomal region of M wolfei encoding the putative prophage was found to be deleted for two noncontiguous segments of the phage ψM1 genome and thus encompassed only 80 to 90 of the ψM1 DNA The prophage region was mapped to a 30 kb restriction fragment on the physical map of the M wolfei chromosome A randomly chosen DNA fragment was cloned from phage ψM1 DNA as was its homologous counterpart from the chromosome of M wolfei The 126bp region present in both clones exhibited 100 sequence identity
