aCalculated with the program INTERHLX
bProtein Data Bank accession number
cTo facilitate a comparison with five-helix SAM domains, the helix order of 2JMT, 1FLX and 1P68 is defined as H1-H2-H4-H5
dAverage angles are calculated only for the five-helix SAM domains
eStandard deviations are calculated only for the five-helix SAM domains
