fussnote | A cholinesterase fraction (S"1) having a sedimentation coefficient of 2.9 S was found to be released from myosin solution by a heat treatment carried out at 53 ^o and pH 6.2 for 5 minutes. It could be resolved by dialyzing into a P"1-fraction of 3.76 S precipitating at a low ionic strength, and a D"1-fraction of 1.45 S remaining in solution under the same conditions. The cholinesterase activity has mainly passed into the P"1-fraction or, after its heat treatment, into the P"2-fraction. The specific activities of the P"1 and P"2 fractions were much more higher (55 and 120 μg acetylcholine (ACh) per milligram protein per hour, respectively) than that of the original myosin solution (8-10 μg Ach/mg prot./hour) or D"1-fraction (5-6 μg ACh per milligram protein per hour).If previous to heat treatment a short tryptic digestion was applied, the properties of heat-supernatant (S"1) principally changed as at reducing of its ionic strength by dialyzing, the great part of its protein content and cholinesterase activity was obtained in the D"1-fraction. In this case the specific activity of the D"1-fraction was considerably more (50 μg Ach/mg prot./hour) than that of the P"1-fraction (17 μg Ach/mg prot./hour). |
