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).

tubulin-tyrosine carboxypeptidase

Catalysis of the reaction: C-terminal L-alpha-aminoacyl-L-glutamyl-L-glutamyl-L-tyrosyl-[tubulin] + H2O = C-terminal L-alpha-aminoacyl-L-glutamyl-L-glutamyl-[tubulin] + L-tyrosine.

protein-glutamic acid ligase activity, elongating

Catalytic reaction :(L-glutamyl)n-L-gamma-glutamyl-L-glutamyl-[protein] + ATP + L-glutamate = (L-glutamyl)n+1-L-gamma-glutamyl-L-glutamyl-[protein] + ADP + H+ + phosphate.

cyanophycin synthetase activity (L-arginine-adding)

Catalysis of the reaction: ATP + [L-Asp(4-L-Arg)]n-L-Asp + L-arginine = ADP + phosphate + [L-Asp(4-L-Arg)]n+1.

cyanophycin synthetase activity (L-aspartate-adding)

Catalysis of the reaction: ATP + [L-Asp(4-L-Arg)]n + L-Asp = ADP + phosphate + [L-Asp(4-L-Arg)]n-L-Asp.

obsolete alanylglutamate dipeptidase activity

OBSOLETE. Catalysis of the reaction: L-alanyl-L-glutamate + H2O = L-alanine + L-glutamate.

cystathionine gamma-synthase activity

Catalysis of the reaction: L-cysteine + O-succinyl-L-homoserine = H+ + L,L-cystathionine + succinate.

5-methyltetrahydropteroyltriglutamate-homocysteine S-methyltransferase activity

Catalysis of the reaction: 5-methyltetrahydropteroyltri-L-glutamate + L-homocysteine = L-methionine + tetrahydropteroyltri-L-glutamate.
