•Karenia brevis strains with a 10 fold difference in toxin content were compared.•Proteins from a low toxin strain show a 25% increase in reduced cysteine.•The enzymes Dde, MGDG synthase and Trx are more reduced in low toxin cultures.•K. brevis with low toxin quota produces twice the MGDG when norma...
