Agarase and Agarose

Agarase Specificity

Agarose

Agarose is the principal neutral gelling component of agar extracted from algae. Agarose is a complex range of polysaccharide chains composed of alternating α-(1-3)-D-galactosyl-β-(1-4)-anhydro-L-galactosyl units.1

Agarase

EC# 3.2.1.81
Synonym: agarose 3-glycanohydrolase

Agarase catalyzes the hydrolysis of 1,3-b-D-galactosidic linkages in agarose, giving the tetramer as the predominant product. 1

Alginate Lyase and Alginic Acid

Alginate Lyase and Alginic Acid

Composed of blocks of β-D-(1-4) mannuronic acid homopolymeric regions (MMMM…), α-L-(1-4)guluronic acid (GGGG…) homopolymeric regions, and alternating copolymer regions of β-D-(1-4) mannuronic acid - α-L-(1-4)-guluronic acid (GMGMGM…). Bacterial alginic acid can be acetlylated at the 2 or 3 positions on mannuronic acid.
