Table 1. Freeze-fracture particle analysis of BetP wild-type, BetP-W101A/T351A and BetPΔC-W101A/T351A.

	Density (particles/μm²)	Diameter (nm)*	Area (nm²)^‡
BetP WT	368.0±15.0	10.0±0.8	78.5±0.5
BetP-W101A/T351A	331.0±19.0	5.1±0.7	20.4±0.4
BetPΔC-W101A/T351A	295.0±12.0	5.0±0.7	19.6±0.4
^*Diameters were corrected for the thickness of the platinum–carbon film by subtracting 2.5±0.8 nm from the mean diameters obtained from the frequency histograms; ^‡Cross-sectional area was obtained by assuming a circular geometry for the particles. WT, wild type.
