zingiber phillippsiae/tyrosine

We screened water and methanol extracts of 28 Indonesian medicinal plants for their protein tyrosine phosphatase 1B (PTP1B) inhibitory activities. Nine water extracts, i.e., Alstonia scholaris leaf, Blumea balsamifera, Cinnamomum burmannii, Cymbopogon nardus, Melaleuca leucadendra, Phyllanthus

A first attempt was made to study the fluorescence quenching, structure and unfolding nature of the purified Zingiber montanum (J.Koenig) Link ex A.Dietr. cysteine protease glycoprotein (ZCPG). ATR-IR spectra showed the presences of amide groups along with carbohydrate stretch indicating the

A cysteine protease from ginger rhizome (GP-II) cleaves peptides and proteins with proline at the P(2) position. The unusual specificity for proline makes GP-II an attractive tool for protein sequencing and identification of stably folded domains in proteins. The enzyme is a 221 amino acid
