The directed movement of proteins from the endoplasmic reticulum.

Enables the transfer of a solute or solutes from one side of a membrane to the other according to the reaction: peptide(out) + H+(out) = peptide(in) + H+(in), up its concentration gradient. The transporter binds the solute and undergoes a series of conformational changes. Transport works equally well in either direction and is driven by hydrogen ion movement.

Enables the transfer of oligopeptide from one side of a membrane to the other. In high-affinity transport the transporter is able to bind the solute even if it is only present at very low concentrations. Oligopeptides are molecules that contain a small number (2 to 20) of amino-acid residues connected by peptide linkages.

OBSOLETE. Catalysis of the stereospecific transfer of asparagine or glutamine across a biological membrane.

OBSOLETE. (Was not defined before being made obsolete).

Enables the transfer of glutamine from one side of a membrane to the other. In high-affinity transport the transporter is able to bind the solute even if it is only present at very low concentrations.

OBSOLETE. The proteolytic degradation of proteins in the cytosol that contributes to apoptosis.

Binding to a molybdate ion (MoO4 2-).

The process in which thiamine is transported across a membrane. Thiamine is vitamin B1, a water soluble vitamin present in fresh vegetables and meats, especially liver.

Binding to thiamine (vitamin B1), a water soluble vitamin present in fresh vegetables and meats, especially liver.

Binding to thiamine pyrophosphate, the diphosphoric ester of thiamine. Acts as a coenzyme of several (de)carboxylases, transketolases, and alpha-oxoacid dehydrogenases.

Binding to taurine.

Binding to alkanesulfonates, the anion of alkanesulfonic acids, sulfonic acid derivatives containing an aliphatic hydrocarbon group.

OBSOLETE. (Was not defined before being made obsolete).

Enables the transfer of thyroid hormones from one side of a membrane to the other. Thyroid hormone are any of the compounds secreted by the thyroid gland, largely thyroxine and triiodothyronine.

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

Enables the transfer of organic anions from one side of a membrane to the other, in a sodium independent manner.

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

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

The modification of two peptidyl-tyrosines to form a 3'-(O4'-L-tyrosinyl)-L-tyrosine protein cross-link.
