Imagine the main chain of a protein bends back on itself, so that two amino acid residues R₁ and R₂ come close to each other. 1 In the table below are four possibilities for what R₁ and R₂ might be. In each case, decide whether a specific interaction could form between the residues. If a specific interaction could form, give the name of the interaction. R₁ specific interaction? R₂ ○ yes lysine glutamate no name of specific interaction ☐ threonine threonine ○ yes ○ no leucine glutamine ○ yes O no ○ yes cysteine cysteine O no
