Methylphosphonate mapping of phosphate contacts critical for RNA recognition by the human immunodeficiency virus tat and rev proteins.

C E Pritchard et al.

Nucleic acids research, 22(13), 2592-2600 (1994-07-11)

The HIV-1 regulatory proteins tat and rev are both RNA binding proteins which recognize sequences in duplex RNA which are close to structural distortions. Here we identify phosphate contacts which are critical for each binding reaction by use of a

Application of hydrophilic-interaction liquid chromatography to the separation of phosphorylated H1 histones.

H Lindner et al.

Journal of chromatography. A, 782(1), 55-62 (1998-01-24)

A new two-step high-performance liquid chromatography (HPLC) procedure has been developed to separate modified histone H1 subtypes. Reversed-phase (RP) HPLC followed by hydrophilic-interaction liquid chromatography (HILIC) was used for analytical and semi-preparative scale fractionation of multi-phosphorylated H1 histone subtypes into

Methodological aspects of methylphosphonic acid analysis: Determination in river and coastal water samples.

Constantin Lohrer et al.

Talanta, 211, 120724-120724 (2020-02-20)

Methylphosphonic acid (MPn) is suspected to play an important role in aquatic systems like rivers or the open ocean. To gain more insights into the importance of MPn, e.g., for the aquatic phosphorus cycle, an analytical method for its quantitative
