title: Distribution and possible function of the marine alkaloid, norzoanthamine, in the zoanthid Zoanthus sp. using MALDI imaging mass spectrometry.
abstract: The role of the marine alkaloid, norzoanthamine, in the colonial zoanthid Zoanthus sp. was previously unknown. High concentrations of norzoanthamine are present in the epidermal tissue of Zoanthus sp., as determined using protonated molecular ion peak mapping of norzoanthamine by matrix-assisted laser desorption/ionization mass spectrometry and high-performance liquid chromatography quantification. Sodium dodecylsulfate polyacrylamide gel electrophoresis experiments indicate that norzoanthamine increases the resistance of collagen to damage from UV light, probably not via UV light absorption, but by strengthening collagen itself, thus suggesting that collagen strengthening may be the function of norzoanthamine in Zoanthus sp.
