Phase residuals after refinement of tube center and out-of-plane tilt for the two types of Bor1p helical assemblies. (A) Phase residuals for 57 Type 1 tubes are lowest when |n(1,0)| = |n(0,1)|+1. (B) Phase residuals for 34 Type 2 tubes are lowest when |n(1,0)| = |n(0,1)|+2, with a slight preference for the (−10,8) indexing scheme. The very high residuals for the last three indexing schemes illustrate that the two types of tubes have distinct helical symmetries. All data represent the mean phase residual and standard error of the mean.
