Split beta-alpha-beta motif

This motif is a beta-alpha-beta motif in which the strands lie parallel in the same sheet, but are non-adjacent and not hydrogen bonded together. The number of intervening strands is usually small. These motifs are common in alpha-beta proteins with an antiparallel sheet.
