title: Immunological comparison of ribosomal proteins from archaebacteria.
abstract: Antisera were raised in rabbits against ribosomal proteins of Methanobacterium bryantii and used to analyze immunological relationships to ribosomes from other archaebacteria, from eubacteria, and from yeasts. Cross-reaction could be detected within the methanogens and with a member of the extreme halophiles; the degree of immunological similarity reflected the relationship delineated by 16S ribosomal ribonucleic acid oligonucleotide analysis (Fox et al., Science 209:457-463, 1980). With the methods and the anti-total-protein sera employed, there was no detectable cross-reaction with ribosomal proteins or ribosomes from Sulfolobus sp., eubacteria, or yeast.
