A MEMBRANE FRACTION FROM RED HAKE (UROPHYCIS CHUSS) MUSCLE CATALYZING THE CONVERSION OF TMAO (TRIMETHYLAMINE OXIDE) TO DMA (DIMETHYLAMINE) AND FORMALDEHYDE.

Author(s) : PARKIN K. L., HULTIN H. O.

Summary

A MICROSOMAL FRACTION HAS BEEN ISOLATED FROM SKELETAL MUSCLE OF RED HAKE WHICH IS CAPABLE OF CONVERTING TMAO TO DMA AND FORMALDEHYDE IN THE PRESENCE OF IRON AND ASCORBATE AND/OR CYSTEINE. THE RATE OF PRODUCTION OF DMA WAS GREATER AT 267 K (-6 DEG C) THAN AT TEMPERATURES ABOVE FREEZING. CUSK (BROSME BROSME), A GADOID WHICH PRODUCES DMA LESS RAPIDLY THAN RED HAKE, YIELD MICROSOMES WITH ABOUT 10% OF THE ACTIVITY OF THAT FROM RED HAKE. THE MICROSOMES FROM WINTER FLOUNDER (PSEUDOPLEURONECTES AMERICANUS) WHICH DO NOT PRODUCE DMA DURING FROZEN STORAGE, HAVE LESS THAN 1% OF THE ACTIVITY OF RED HAKE.
