Identifying tandem Ankyrin repeats in protein structures

Table 1 Characteristic features of Ankyrin repeat proteins

Length	1 ^sthelix	turn/coil	2 ^ndhelix	H-T-H core	Dist. between peak positions	ANK motif
Maximum	12	8	21	34	15	49
Minimum	3	1	4	13	5	19
Mean	7.7	2.4	9.8	20	8.6	31.2

Variations in the length of the secondary structure elements and the distance between two peaks in the A _levc profile of the ANK motif for a dataset of 58 non-redundant protein structures is summarized.
