Abstract:
:Methanococcus voltae produces two flagellins of molecular weight 31,000 and 33,000. Amino acid analysis as well as peptide mapping with cyanogen bromide, chymotrypsin and Staphylococcus aureus V-8 protease indicates that the two flagellins are distinct. N-terminal sequencing of the 31,000 Mc. voltae flagellin as well as the 24,000 and 25,000 molecular weight flagellins of Methanospirillum hungatei GP1 shows an extensive homology with the reported N-terminus of the flagellins from Halobacterium halobium, deduced from the nucleotide sequence of the cloned genes. However, the N-termini of all three sequenced methanogen flagellins lack a terminal methionine and start at position 13 from the N-terminus of H. halobium flagellins. This initial 12 amino acid stretch may be a leader peptide which is subsequently cleaved to generate the mature flagellin, which could suggest flagellar assembly in archaebacteria occurs by a mechanism distinct from that in eubacteria. The high degree of conservation of the N-terminus of the flagellins from Mc. voltae, Msp. hungatei and H. halobium suggests an important role for this sequence, and that the archaebacteria share a common mechanism for flagellar biosynthesis.
