GH145 is a deleted family
This family has been reclassified as Polysaccharide Lyase Family 42. Two members of the family from Bacteroides species were originally shown to have hydrolase activity catalyzed by a semi-conserved active site on the posterior side of the beta-propeller structure [1]. Subsequently, lyase activity on alpha-L-Rha-1,4-alpha-D-GlcA via a well-conserved active site on the anterior surface, with strong similarity to PL24 and PL25, was demonstrated in fungal [2] and bacterial [3] homologs.
