Agar Degradation By Microorganisms And Agar-Degrading Enzymes

Agar Degradation By Microorganisms And Agar-Degrading Enzymes Chi, Won-Jae, Yong-Keun Chang, and Soon-Kwang Hong.Applied microbiology and biotechnology 94 (2012): 917-930.

Agar is a mixture of heterogeneous galactans consisting mainly of 3,6-anhydro-galactose (or -galactose-6-sulfate), -galactose, and -galactose (in the conventional form 3,6-anhydro- -galactose or -galactose-6-sulfate) linked alternately by β-(1,4) and α-(1,3) bonds. It is a major component of the cell wall of red algae and has been used in various laboratory and industrial applications due to its gelling properties. Agar-hydrolyzing microorganisms usually produce agarases, which catalyze the hydrolysis of agar. Several agarases have been identified in microorganisms of different genera. Based on their cleavage pattern, they are divided into three types: α-agarase, β-agarase, and β-porphyrinase.
α-Agarases (EC 3.2.1.158) - related to the α-agarase degradation pathway by selective cleavage of α-(1,3) glycosidic bonds (LA-α(1,3)-G) - have been reported from two marine microorganisms (Alteromonas). α-Agarase AgaA purified from culture broth of A. agarlyticus hydrolyzes agarose to agarotetraose and agarohexaose. The native enzyme forms a homodimer with an estimated molecular weight of 360 kDa. α-Agarase AgaA33 from Thalassomonas sp. JAMB-A33 (renamed Thalassomonas agarivorans, isolated from deep-sea sediments at a depth of 230 m) was determined to have a molecular weight of 87 kDa and exists as a monomer. The enzyme is an endo-α-agarase that hydrolyzes agarose to agarotetraose. It can hydrolyze the α-(1,3) glycosidic bonds of not only agarose, but also agarohexaose, neoagarohexaose and porphyrin.
