Surface activity (γlv) of SC3 and its derivatives at the water-air interface (100 μg ml⁻¹) and wettability at both sides of the hydrophobin membranes^a

Hydrophobin	Mean degrees ± SEM		γlv (mJ m−2)	Rodlet diam (nm)
	θ hydrophobic side (in vitro, in vivo)	θ hydrophilic side
SC3	115 ± 12, 121 ± 6	44 ± 1	32	10
RGD-SC3	122 ± 4, 120 ± 4	44 ± 2	32	10
TrSC3	NDd, 119 ± 3	73 ± 3	32	8-10
RGD-TrSC3	120 ± 3, 123 ± 1	68 ± 3	30	8-10
SC3−Glyb	ND, ND	66 ± 6	32c	-e

^aWettability is expressed as the water contact angle (θ). Note that the surface tension of water is 72 mJ m⁻².

^bThat is, chemically deglycosylated SC3.

^cThe surface activity was measured at 22 μg ml⁻¹.

^dND, not determined.

^e-, No rodlets were observed.
