A comparison of the distribution of enzymatically and non-enzymatically produced lead phosphate in insect flight muscle.
Lead phosphate precipitates were produced in indirect flight muscles of Phormia regina by sequential incubation in solutions containing lead and inorganic phosphate and their distribution was compared with those produced by ATP hydrolysis in the presence of lead. Enzymatically produced precipitates were associated almost exclusively with thick filaments. Non-enzymatically produced precipitates were associated with thick filaments but were also found associated with thin filaments in significant numbers.
