Potassium pyroantimonate (PA) binding on GONRs surface had an inhibitory effect on the catalysis of GONRs.
But pyroantimonate (223.74 Da) penetrates the intercellular spaces in excised gills of the fresh-water mussel Elliptio complanatus, presumably through septate junctions in the ctenidial epithelium (Satir and Gilula, 1970; see also Machin, 1977; Stommel, 1984a).
Some small fibrils, especially in the plumula, were best fixed in a 1% osmium tetroxide solution in 0.05 M cacodylate buffer saturated with potassium pyroantimonate. This fixation will be called osmium fixation.
Suzuki (4) suggests that calcium-containing pyroantimonate precipitates found along the inner membrane surface could be a [Ca.sup.2+] source during E-C coupling as well.
