Secondary structure composition of Ejl amidase derived from prediction methods CD and IR spectroscopies

Secondary structure prediction		CD			IR
			%a			%c
Component	%	Component	−	+	Component	−	+
β-Strand	35 ± 4	β-sheetb	36	42	β-sheet and unordered	58	48
Turns, loops, others	52 ± 2	turns	20	19	turns	14	12
		Non regular structures	32	31
α-Helix	10 ± 2	α-helix	12	8	α-helix and loops	28	40

The signs (−) and (+) indicate the absence or presence of choline.

^a Errors are within ±10% of the estimated value.

^b Antiparallel and parallel β-sheet are, respectively, 31 and 5% without choline, and 37 and 5% with choline.

^c Errors are within ±5% of the estimated value.
