Borrelia burgdorferi spends a significant proportion
of its life cycle within an ixodid tick, which has a cuticle containing chitin, a polymer of N-acetylglucosamine (GlcNAc). The
B. burgdorferi celA, celB, and
celC genes encode products homologous to
transporters for cellobiose and chitobiose (the dimer subunit of
chitin) in other bacteria, which could be useful for bacterial nutrient
acquisition during growth within ticks. We found that chitobiose
efficiently substituted for GlcNAc during bacterial growth in culture
medium. We inactivated the celB gene, which
encodes the putative membrane-spanning component of the transporter,
and compared growth of the mutant in various media to that of its
isogenic parent. The mutant was no longer able to utilize chitobiose,
while neither the mutant nor the wild type can utilize cellobiose. We
propose renaming the three genes chbA,
chbB, and chbC, since they probably
encode a chitobiose transporter. We also found that the
chbC gene was regulated in response to growth
temperature and during growth in medium lacking GlcNAc.
