[[https://www.uniprot.org/uniprot/AGAD_ZOBGA AGAD_ZOBGA]] Cleaves the beta-1,4-linkages between beta-D-galactose and alpha-L-3,6-anhydro-galactose residues in agarose. Cleaves agarose in a random manner with retention of the anomeric-bond configuration, producing beta-anomers that give rise progressively to alpha-anomers when mutarotation takes place. Requires at least 4 consecutive agarose units and is highly intolerant to modifications.<ref>PMID:22778272</ref>
