À La Mode Component ID: Cpro_riboseC2endo_O3H_O5H_anti_+sc

Component name: (view abbreviated component mmCIF) (view full component mmCIF)

protonated cytidine

Component description:

Model constructed for protonated cytidine from subcomponents for protonated base and sugar. The sugar is ribose in the C2'-endo conformation, and geometries for the gamma torsion angle (synclinal), the chi torsion angle (antiperiplanar), and the C3*-O3* and C5*-O5* bonds are inserted from other models.

Component formula and formula weight:
