Naming of phosphate oxygens in nucleotides

[Ton Rullmann]

A draft-proposal "Recommendations for presentations of NMR structures of
proteins and nucleic acids", prepared by a IUPAC-IUBMB-IUPAB Interunion
Task Group says:

The phosphorus-bound oxygens are named O3', O5', OP1 and OP2, such that, when
looking down the O3'-P bond, the clockwise order of atoms is: O5', OP1, OP2.

The proposal refers to the recommendations published in
Eur. J. Biochem. (1982) 131: 9-15.
but possibly the statement given above is not from that paper (I did not
check).
