The paper published by [Nat Struct Mol Biol 25(2):131-134 (2018)] reports some polar clasps for these two crystal structures, and \"an intersheet hydrogen bond between Tyr169 and the backbone carbonyl of Asn171 on an opposing strand.\" - this hydrogen bond is not between the neighbouring Chain B and Chain A directly.
