zingiber corallinum/プロリン

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

The ginger proteases (GP-I and GP-II), isolated from the ginger rhizome Zingiber officinale, have an unusual substrate specificity preference for cleaving peptides with a proline residue at the P2 position. The complete amino-acid sequence of GP-II, a glycoprotein containing 221 amino acids, and

The effect of foliar salicylic acid (SA) applications (10⁻³ and 10⁻⁵ M) on activities of nitrate reductase, guaiacol peroxidase (POD), superoxide dismutases (SOD), catalase (CAT) and proline enzymes and physiological parameters was evaluated in two ginger varieties (Halia Bentong and Halia Bara)
