OBSOLETE. Any of a set of activities involved in the complement cascade.

Catalysis of the reaction: protein glutamine + alkylamine = protein N5-alkylglutamine + NH3. This reaction is the formation of the N6-(L-isoglutamyl)-L-lysine isopeptide, resulting in cross-linking polypeptide chains; the gamma-carboxamide groups of peptidyl-glutamine residues act as acyl donors, and the 6-amino-groups of peptidyl-lysine residues act as acceptors, to give intra- and intermolecular N6-(5-glutamyl)lysine cross-links.

Any process that modulates the frequency, rate or extent of phospholipid efflux.

Any process that modulates the frequency, rate or extent of neurofibrillary tangle assembly.

Any process that activates or increases the frequency, rate or extent of phospholipid efflux.

Any process that activates or increases the frequency, rate or extent of neurofibrillary tangle assembly.

Any process that stops, prevents or reduces the frequency, rate or extent of neurofibrillary tangle assembly.

OBSOLETE. Catalysis of the preferential cleavage of Arg-Gly; activates fibrinogen to fibrin and releases fibrinopeptide A and B.

OBSOLETE. Catalysis of the degradation of blood coagulation factors Va and VIIIa.

Any process that stops, prevents or reduces the frequency, rate or extent of phospholipid efflux.

OBSOLETE. Catalysis of the selective cleavage of Arg-Xaa and Lys-Xaa bonds, including Lys-Arg and Arg-Ser bonds in (human) kininogen to release bradykinin.

OBSOLETE. Catalysis of the selective cleavage of Arg-Ile bonds in factor VII to form factor VIIa and factor XI to form factor XIa.

OBSOLETE. Catalysis of the selective cleavage of Arg-Ala and Arg-Val bonds in factor IX to form factor IXa.

OBSOLETE. Catalysis of the preferential cleavage of Arg-Thr and then Arg-Ile bonds in prothrombin to form thrombin, and on factor VII, which it converts to a two-chain form (factor VIIa).

OBSOLETE. Catalysis of the selective cleavage of the Arg-Ile bond in factor X to form factor Xa.

OBSOLETE. Catalysis of the selective cleavage of one Arg-Ile bond in factor X to form factor Xa, and on factor IX to form factor IXa beta.

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

The chemical reactions and pathways resulting in the breakdown of compounds derived from histidine, 2-amino-3-(1H-imidazol-4-yl)propanoic acid.

OBSOLETE. A protein involved in an antiviral response.

The pathway resulting in the formation of ergothioneine from histidine via a set of steps in which gamma-glutamyl-hercynylcysteine sulfoxide is formed as an intermediate.
