Succinimide formation from aspartyl and asparaginyl peptides as a model for the spontaneous degradation of proteins.
Legumain (LGMN) also known as asparaginyl endopeptidase (AEP) is implicated in various cancer such as prostrate, breast, colon, lung, ovarian, central nervous system (CNS) related cancers, melanoma and lymphoma (1).
Amarnaths team investigated how PD-1 blocked these cancer fighting cells; they found that PD-1 specifically downregulated a new enzyme called asparaginyl endopeptidase (AEP) which was key to shifting the balance between cancer fighting cells and regulatory T cells within the melanoma tumour environment.
The most common is Jo-1 (histidyl) (15%-30% prevalence), followed by PL-7 (threonyl) and PL-12 (alanyl), with a prevalence of 5% to 10%, followed by EJ (glycyl), OJ (isoleucyl), KS (asparaginyl), Zo (phenylalanyl), and YRS (tyrosyl) (all with prevalences of 1%-5%).

LGMN, legumain, has a strict specificity for hydrolysis of asparaginyl bonds required for normal lysosomal protein degradation in renal proximal tubules and plays a role in the regulation of cell proliferation via its role in EGFR degradation; VDR, vitamin D (1,25-dihydroxyvitamin D3), is a nuclear receptor that mediates the action of vitamin D3 by controlling the expression of hormone-sensitive genes and plays a central role in calcium homeostasis; HP, haptoglobin, captures and combines with free plasma hemoglobin to allow hepatic recycling of heme iron and to prevent kidney damage.

Transient metal ions like nickel and cobalt are known to mimic cellular hypoxia mainly due to the inhibition of prolyl hydrolases (PDHs) and asparaginyl hydrolase (factor-inhibiting HIF (FIH)).
