Abstract
Flagellin genes from the anaerobic Gram-negative beer-spoilage bacteria Pectinatus cerevisiiphilus and Pectinatus frisingensis were sequenced and the flagellin proteins initially characterized. Protein microsequencing led to the design of two degenerate PCR primers that allowed the P. cerevisiiphilus flagellin gene to be partially sequenced. A combination of PCR and Bubble PCR was then used to sequence the flagellin genes of three isolates from each species. Cloning and gene expression, followed by immunoblotting, confirmed the gene identities as flagellin. Analysis of the gene sequences revealed proteins similar to other bacterial flagellins, including lengths of 446 or 448 amino acids, putative sigma 28 promoters, and a termination loop. Antibody binding studies with isolated flagella correlated with gene sequence comparisons, with both indicating that the P. cerevisiiphilus isolates studied are very similar but that the P. frisingensis isolates show greater variation. Purified flagellins were found to be glycosylated, probably through an O linkage. Phylogenetic analysis revealed greater diversity within the flagellin sequences than within the 16S rRNA genes. Despite the Gram-negative morphology of Pectinatus, this genus proved most closely related to Gram-positive Firmicutes. © 2005 NRC Canada.
