Dammarane-type saponins from Gynostemma pentaphyllum.

abstract：:Two cell wall proteins from chickpea, known to be rapidly insolubilised by an elicitor-stimulated oxidative burst in-vivo, were purified from suspension cells. N-terminal protein sequencing revealed them as a proline-rich protein and an extensin-like protein. Oxidative cross-linking could be modelled in an in vitro sy...
