Relative activities of LbBgl and BaBgl in organic and inorganic buffers at pH 7^d

Buffer	Relative enzyme activity (%)
	LbBgl	BaBgl
Tris (100 mM)	100 ± 0	100 ± 2
McIlvainea	158 ± 2	174 ± 1
Phosphate buffer (100 mM)	127 ± 2	143 ± 1
MOPSb (100 mM)	163 ± 2	158 ± 2
HEPES (100 mM)	145 ± 0	132 ± 1
Succinic acid (100 mM)	124 ± 2	135 ± 2
Britton-Robinson bufferc	136 ± 1	141 ± 1

^aCitrate-phosphate buffer according to reference 35.

^bMorpholinepropanesulfonic acid.

^cDescribed in reference 28.

^dRelative activities of LbBgl and BaBgl in organic and inorganic buffers at pH 7 were determined with pNP-β-d-glucopyranoside at 37°C. All values represent the means from triplicate determinations ± standard deviations.
