| Abstract: |
| There are genome sequences of three Arthrospira platensis strains，an Arthrospira maxima strain，
a Spirulina subsalsa strain，an Arthrospira sp. strain in the NCBI genome database up to date. 32 glycosidase genes
can be retrieved from the 6 Spirulina genome sequences，which have 260-1 084 amino acids in length. By BLAST
analysis in GenBank，the similarity with the known sequences from the non-Spirulina species was 49%-84%.
Phylogenetic analysis indicated that the 32 glucosidase genes were divided into 8 groups，and the other 3 genes
constituted an independent evolutionary branch，respectively. The enzyme function prediction of these glucosidase
genes showed that they belonged to 8 glucosidase families: GH3，GH9，GH13，GH23，GH25，GH38，GH57，
GH104，and 8 kinds of glycosidase catalytic activity: cellulase，lysozyme，α-mannosidase，α-amylase，
pullulanase，1，4-α-glycogen branching enzyme，peptidoglycan binding function，β-glucosidase. |
