Which of the following is correct regarding the β turns

(1) In Type I β turn i+1 lies in RHH region while i+2 lies near BS region

(2) In Type II β turn i+1 lies in BS while i+2 lies in below LHH

(3) In Type I’ β i+1and i+2 in near LHH which virtually not allowed region for most of amino acid except Gly

(4) In Type II’ β i+2 lies at 00 psi and i+1 in lower right region both i+2 and   i+1  must be Gly
