| Research Abstract |
We have clarified that four chitinases (ChiA, ChiB, ChiC, and ChiD), three β-N-acetylglucosaminidases (GlcNAcases A, B, and C), a transglycosylative enzyme (Hex99), a chitin-binding protein (Cbp1), and two proteases (AprIV and MprIII) are involved in chitin degradation of the marine bacterium, Alteromonas sp. strain O-7. Recently, the glmS gene coding for one of the key enzymes of GlcNAc utilization was cloned, and the function and regulation of the enzyme was clarified. Furthermore, the genome analysis of strain O-7 was performed by Illumina Genome Analyzer. The homology search indicated that there are additional chitinase-, chitin-binding protein-, and N-acetylglucosaminidase-encoding genes in the genome.
