lithium ion binding

Binding to a lithium ion (Li+).

lithium ion transmembrane transport

The directed movement of lithium ions (Li+) across a membrane.

lithium:proton antiporter activity

Enables the transfer of a solute or solutes from one side of a membrane to the other according to the reaction: Li+(in) + H+(out) = Li+(out) + H+(in).

sulfiredoxin activity

Catalysis of the reaction: peroxiredoxin-(S-hydroxy-S-oxocysteine) + ATP + 2 R-SH = peroxiredoxin-(S-hydroxycysteine) + ADP + phosphate + R-S-S-R.

cellular response to lithium ion

Any process that results in a change in state or activity of a cell (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of a lithium (Li+) ion stimulus.

eriodictyol 3'-O-methyltransferase activity

Catalysis of the reaction: (S)-eriodictyol + S-adenosyl-L-methionine = (S)-homoeriodictyol + H+ + S-adenosyl-L-homocysteine.

(S)-coclaurine-N-methyltransferase activity

Catalysis of the reaction: S-adenosyl-L-methionine + (S)-coclaurine = S-adenosyl-L-homocysteine + (S)-N-methylcoclaurine.

obsolete glutathione oxidoreductase activity

OBSOLETE. Catalysis of the reaction: protein-S-S-glutathione + glutathione-SH = protein-SH + glutathione-S-S-glutathione.

(S)-scoulerine 9-O-methyltransferase activity

Catalysis of the reaction: (S)-scoulerine + S-adenosyl-L-methionine(1+) = (S)-tetrahydrocolumbamine + S-adenosyl-L-homocysteine + H+.

3'-hydroxy-N-methyl-(S)-coclaurine 4'-O-methyltransferase activity

Catalysis of the reaction: S-adenosyl-L-methionine + 3'-hydroxy-N-methyl-(S)-coclaurine = S-adenosyl-L-homocysteine + (S)-reticuline.
