abstract：:The gene encoding the fimbrial subunit protein of Bacteroides gingivalis 381, fimbrilin, has been cloned and sequenced. The gene was present as a single copy on the bacterial chromosome, and the codon usage in the gene conformed closely to that expected for an abundant protein. The predicted size of the mature protein...
