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).

obsolete 1-phenanthrol methyltransferase activity

OBSOLETE. Catalysis of the reaction: 1-phenanthrol + X-CH3 = X + 1-methoxyphenanthrene.

poly(3-hydroxybutyrate) depolymerase activity

Catalysis of the reaction: H2O + poly[(R)-3-hydroxybutanoate](n) = poly[(R)-3-hydroxybutanoate](x) + poly[(R)-3-hydroxybutanoate](n-x); x is 1-5.

poly(3-hydroxyoctanoate) depolymerase activity

Catalysis of the reaction: H2O + poly[(R)-3-hydroxyoctanoate](n) = poly[(R)-3-hydroxyoctanoate](x) + poly[(R)-3-hydroxyoctanoate](n-x); x is 1-5.

collagen type X trimer

A collagen homotrimer of alpha1(X) chains; type X collagen triple helices form hexagonal networks (sheets).

oxidoreductase activity, acting on X-H and Y-H to form an X-Y bond

Catalysis of an oxidation-reduction (redox) reaction in which X-H and Y-H form X-Y.

Atg12 transferase activity

Catalysis of the transfer of ATG12 from one protein to another via the reaction X-ATG12 + Y = Y-ATG12 + X, where both X-ATG12 and Y-ATG12 are covalent linkages.

SUMO transferase activity

Catalysis of the transfer of SUMO from one protein to another via the reaction X-SUMO + Y = Y-SUMO + X, where both X-SUMO and Y-SUMO are covalent linkages.
