Substrate specificities
PL30 is a small family (38 sequences), exclusively bacterial belonging to the phylum Bacteroidetes. The founding member of family 30, and the only one characterized, belongs to Bacteroides cellulosilyticus WH2 (BcellWH2_02524, WP_029426181.1). The activity was measured against hyaluronic acid by following the absorbance at 232nm. The increase in absorbance confirms that BcellWH2_02524 is a hyaluronan lyase (4.2.2.1), probably using the by β-elimination process like all PL families [1].
