The gene (rhaM) encoding the alpha-L-rhamnosidase of Sphingomonas paucimobilis FP2001 was cloned, sequenced, and expressed in Escherichia coli. The rhaM consisted of 3,354 nucleotides and had a promoter and Shine-Dalgarno sequences typical in bacteria. The rhaM encoding a protein (Rham) deducted from the sequence consisted of 1,117 amino acids and had a putative signal peptide of 25 amino acids. Rham has no similarity to other known rhamnosidases. Rham has a sugar-binding domain of glycoside hydrolase family 2, which has been well conserved in beta-glucuronidase, beta-mannosidase, and beta-galactosidase, in its C-terminal region. Rham is possibly a member of a new bacterial subfamily in glycoside hydrolase family 78 (alpha-L-rhamnosidase). RT-PCR analysis of rhaM mRNA indicated that the induction of alpha-L-rhamnosidase by the addition of L-rhamnose occurred on the transcriptional level.
