PMOs have their bases on the conformers’ exterior, while the uncharged phosphorodiamidate backbone is shielded from solvent. PMOs form non-canonical, stable structures with low base pair and base stack counts. The results …
WebPhophoramidates are highly stable and have a high affinity for their target RNA however they do not activate RNASE H ( Gryaznov et al., 1995, 1996 ). This modification is only useful for situations when only RNA occupancy but not RNA degradation is required, and therefore not widely used. Sign in to download hi-res image Fig. 1. A Morpholino, also known as a Morpholino oligomer and as a phosphorodiamidate Morpholino oligomer (PMO), is a type of oligomer molecule (colloquially, an oligo) used in molecular biology to modify gene expression. Its molecular structure contains DNA bases attached to a backbone of methylenemorpholine rings linked through phosphorodiamidate groups. Morph…

A phosphorodiamidate (or diamidophosphate) is a phosphate that has two of its OH groups substituted by NR 2 groups to give a species with the general formula O=P(OH)(NH 2) 2. The substitution of all three OH groups gives the phosphoric triamides (O=P(NR 2) 3), which are commonly referred to as … See more Phosphoramidates (sometimes also called amidophosphates) are a class of phosphorus compounds structurally related to phosphates (or organophosphates) via the substitution of an OR for a NR2. … See more • Phosphoramidite See more Two examples of natural phosphoramidates are phosphocreatine and the phosphoramidate formed when histidine residues in histidine kinases are phosphorylated.
