“…Both types performed well at 45', though the rate fell off more rapidly in the skeletal protein at temperatures above IS'. He pointed out some inconsistency with the results of Hamoir & Gaspar-Godfroid (1964). The latter heated the tonoactomyosin samples for ten minutes at different temperatures under carefully controlled conditions and cooled them rapidly before carrying out the measurements of ATPase activity at 25".…”

“…L'influence de la chaleur sur la tonomyosine-1 0,075 et la myosine de lapin a été examinée antérieurement par électrophorèse, par ultra centrifugation et au moyen de mesures d'activité atépasique dans di verses conditions (H amoir et G aspar-Godfroid, 1964). Nous nous bornerons ici à préciser les changements de sédimentation que ce traite ment entraîne dans le cas des tonomyosines.…”

“…L'obtention d'une tonomyosine-I 0,53 ne différant apparemment pas de celle isolée d'ex traits de faible force ionique ne permet pas d'exclure la présence, dans le muscle lisse de vertébré, d'une myosine normale précipitant en pré sence de sulfate ammonique neutre entre 35 et 45% de saturation, mais rend toutefois cette éventualité peu vraisemblable. Certains résultats de ce travail ont fait l'objet d'une communication préliminaire ( Hamoir et Pechère, 1964).…”

“…A workable compromise, similar to that used by others (Hamoir & Gaspar-Godfroid, 1964;Megerman, 1974), was to use 0.6 M KC1, 10 mM KPi: 10 mM MgATP, and 0.5 mM DTT, pH 8: The actomyosin precipitate was dissolved in buffered 3 M KC1 and dialyzed without Mg or ATP. These were added to the desired concentration just prior to centrifugation for 30 min at 50000 rpm (Beckman 60 Ti rotor) to remove large aggregates.…”
