Kcat/KM for the four BALP isoforms using the synthetic substrate pNPP at pH 9.8 and at 7.4. The BALP B2 isoform had 35-fold higher activity than the B1 isoform for pNPP at pH 9.8. The same trend was observed with pNPP at pH 7.4. The catalytic activities were higher at pH 9.8, but lower at pH 7.4, when the BALP isoforms were treated with neuraminidase. ■ = BALP isoforms treated with neuraminidase.
