- synaptic vesicle lumen acidification
The acidification of the synaptic vesicle lumen via transport of protons into the vesicle. The resulting electrochemical gradient powers neurotransmitter loading.
- sulfiredoxin activity
Catalysis of the reaction: peroxiredoxin-(S-hydroxy-S-oxocysteine) + ATP + 2 R-SH = peroxiredoxin-(S-hydroxycysteine) + ADP + phosphate + R-S-S-R.
