Details of the two types hydrogen bonds. Red dashed lines represent hydrogen bonds. Water was shown with the CPK model. (a) T242(rhodopsin) side chain and D83(arrestin) side chain; T242(rhodopsin) side chain and D83(arrestin) main chain. (b) Q237(rhodopsin) side chain and R82(arrestin) side chain. (c) V138(rhodopsin) main chain and Y68(arrestin) side chain; R135(rhodopsin) side chain and M76(arrestin) main chain. (d) F146(rhodopsin) main chain and K142(arrestin) side chain; F148(rhodopsin) main chain and K142(arrestin) side chain. (e) the hydrogen bonds between E249(rhodopsin) and L78(arrestin); the hydrogen bonds between V138(rhodopsin) and T79(arrestin); the hydrogen bonds between N145(rhodopsin) and Y68(arrestin). (f) the hydrogen bonds between F146(rhodopsin) and D139(arrestin); the hydrogen bonds between R147(rhodopsin) and Q138(arrestin). (g) the hydrogen bonds between Q236(rhodopsin) and L250(arrestin).
