THE FIRST SUCH TURN IS FROM ARG 15 TO GLU REMARK 400 19. PHE 17 IS IN A LEFT-HANDED ALPHA CONFORMATION. SIDE REMARK 400 CHAIN TO MAIN CHAIN HYDROGEN BONDS ARE RESPONSIBLE FOR REMARK 400 STABILIZING THIS STRUCTURE. THESE INCLUDE N VAL 16 - OD2 REMARK 400 ASP 22, N PHE 17 - OD1 ASP 22, OH TYR 18 - N GLY 116 AND OH REMARK 400 TYR 18 - N LEU 118. THE SECOND TURN IS FROM ARG 37 TO ALA REMARK 400 41 (INCLUDING THE INVERSE GAMMA BEND, TURN 4 BELOW). THIS REMARK 400 IS ALSO STABILIZED BY SIDE CHAIN TO MAIN CHAIN HYDROGEN REMARK 400 BONDING INCLUDING ND2 ASN 43 - O ASP 38, N ASN 43 - OG SER REMARK 400 40. THE LATTER HYDROGEN BOND (SIDE CHAIN TO NH(N+3)) IS REMARK 400 COMMON AT THE BEGINNING OF ALPHA-HELICES. ALSO HOH 139 REMARK 400 LINKS O SER 40 WITH OD1 ASN 39 AND HOH 148 LINKS OD1 ASP 38 REMARK 400 WITH OG SER 40. TURN 6 IS PART OF A LARGER END-OF-HELIX REMARK 400 STRUCTURE FIRST DESCRIBED BY C. SCHELLMAN (1980) IN REMARK 400 *PROTEIN FOLDING* (R.JAENICKE, ED.), PP. 53-61, ELSEVIER, REMARK 400 AMSTERDAM. IT ALSO INCLUDES A HYDROGEN BOND FROM O MET 62 REMARK 400 TO N TYR 67 AND WHICH REQUIRES THE N-1 RESIDUE (LYS 66) TO REMARK 400 BE IN A LEFT-HANDED ALPHA-HELICAL CONFORMATION.
