General Information | Comment | Organism |
---|---|---|
physiological function | enzyme degrades both alginate polymers and oligomers into monomers in an exolytic mode. Isoform OalC6 prefers alpha-L-guluronate blocks, while isoform OalC17 prefers poly beta-D-mannuronate blocks. The combination of OalC6 and OalC17 shows synergistic degradation ability toward both alginate polymers and oligomers | Cellulophaga sp. SY116 |
