Levels of β-galactosidase from gerA-lacZ or gerB-lacZ fusions in spores with or without gerKDbs overexpression^a

Strain	Relevant genotype	β-Galactosidase activity (RFU)b
PS533	Wild-type	335
PS767	gerA-lacZ	10,700
PS4319	gerA-lacZ amyE::PsspB-gerKDbs	9,700
PS3709	gerB-lacZ	6,135
PS4320	gerB-lacZ amyE::PsspB-gerKDbs	5,250

^aSpores of various strains were isolated, decoated, and permeabilized, and 8 × 10⁸ spores were assayed for β-galactosidase as described in Materials and Methods.
