alginate is a linear hetero-polyuronic acid composed of 1,4 linked alpha-L-guluronic acid (G) and beta-D-mannuronic acid. Alginate lyase aly-SJ02 is bifunctional. Aly-SJ02 shows activities toward both polyG (alpha-L-guluronic acid), activity of EC 4.2.2.11, and polyM (beta-D-mannuronic acid). Aly-SJ02 mainly releases dimers and trimers from polyM and alginate, and trimers and tetramers from polyG |

alginate lyase A degrades M and G blocks, and the enzyme activity acting on M block is much more than that of G block, while for alginate lyase B, the enzyme activities on M block are slightly higher than that of G block |
