“…The crystal packing is mediated by the presence of several O—H⋯O hydrogen-bonding inter­actions and while the water mol­ecules form a C (2) (1)(4) chain parallel to the c axis of the unit cell, the pendant hy­droxy groups are engaged in O—H⋯O=C hydrogen bonds described by a C (1) (1)(12) graph-set motif which runs parallel to the a axis.…”

“…The reaction occurs under the restriction that the nucleophilic attack of O, from 3′-OH in the terminal CCA, to C, from C=O in the acyl phosphate linkage, must occur at a Bürgi-Dunitz angle, which is defined as the O–C=O angle of approximately 105°. The extended double helical form results in a steric hindrance at the side chain of the amino acid leading to chiral preference combined with cation coordinations in the amino acid and the phosphate oxygen. …”
