Can tryptophan hydrogen bond

WebNov 1, 2001 · A hydrogen bond was defined as an intermolecular contact, with a maximum donor–acceptor distance of 3.9 Å and a maximum hydrogen–acceptor distance of 2.5 Å (the same relaxed criteria as used in HBPLUS). The angle at the donor (donor–hydrogen–acceptor) was restricted to be between 90 and 180°. WebTryptophan can form hydrogen bonds ….
