This family features the antihypertensive and antiviral proteins BDS-I (Swiss:P11494) and BDS-II (Swiss:P59084) expressed by Anemonia sulcata. BDS-I is organised into a triple-stranded antiparallel beta-sheet, with an additional small antiparallel beta-sheet at the N-terminus [1]. Both peptides are known to specifically block the Kv3.4 potassium channel, and thus bring about a decrease in blood pressure [2]. Moreover, they inhibit the cytopathic effects of mouse hepatitis virus strain MHV-A59 on mouse liver cells, by an unknown mechanism [1].
