- obsolete oligopeptidase A activity
OBSOLETE. Catalysis of the hydrolysis of oligopeptides, with broad specificity. Gly or Ala commonly occur as P1 or P1' residues, but more distant residues are also important, as is shown by the fact that Z-Gly-Pro-Gly-Gly-Pro-Ala is cleaved at the Gly-Gly bond, but not Z-(Gly)5.
- G protein-coupled enkephalin receptor activity
Combining with an enkephalin, and transmitting the signal across the membrane by activating an associated G-protein. A enkephalin is a pentapeptide (Tyr-Gly-Gly-Phe-Met or Tyr-Gly-Gly-Phe-Leu) involved in regulating nociception in the body.
- molybdopterin-synthase sulfurtransferase activity
Catalysis of the reaction: [Molybdopterin-synthase sulfur-carrier protein]-Gly-Gly-AMP + [cysteine desulfurase]-S-sulfanyl-L-cysteine = AMP [molybdopterin-synthase sulfur-carrier protein]-Gly-NH-CH(2)-C(O)SH + cysteine desulfurase.
- obsolete gelatinase A activity
OBSOLETE. Catalysis of the cleavage of gelatin type I and collagen types IV, V, VII, X. Cleaves the collagen-like sequence Pro-Gln-Gly-Ile-Ala-Gly-Gln at the Gly-Ile bond.
- ferricrocin metabolic process
The chemical reactions and pathways involving ferricrocin, a cyclic hexapeptide siderophore with the structure Gly-Ser-Gly-(N5-acetyl-N5-hydroxyornithine)3.
