Highly diverse biomolecules are sulfated by an armada of sulfotransferases that depend on provision of active sulfate
in the form of 3 -phospho-adenosine-5 -phosphosulfate (PAPS) for action.
Generally speaking, a 10% active sulfate
system will require about 1-2% of alkanolamide and 1-3% sodium chloride to reach or exceed a viscosity of 10,000 cps.
reduction in Postgate's Medium B is evidenced by the production of Fe[S.
Toad skin is capable of active sulfate
influx from a Ringer's solution containing 1 mmol [1.
Bidigare and Biggs (1980) determined that active sulfate
loss from the ctenophore Beroe cucumis could be compensated by isosmotic chloride exchange.
The co-substrate and active sulfate
donor was radiolabeled 3'-phosphoadenosine 5'-phosphosulfate (([sup.
