We apologize for Proteopedia being slow to respond. For the past two years, a new implementation of Proteopedia has been being built. Soon, it will replace this 18-year old system. All existing content will be moved to the new system at a date that will be announced here.

Crystal structure of human Cathepsin-S C25S mutant with bound drug

Structural highlights

3mpf is a 2 chain structure with sequence from Homo sapiens. Full crystallographic information is available from OCA. For a guided tour on the structure components use FirstGlance.
Ligands:
Related:	3mpe
Gene:	CTSS (Homo sapiens)
Activity:	Cathepsin S, with EC number 3.4.22.27
Resources:	FirstGlance, OCA, RCSB, PDBsum

Function

[CATS_HUMAN] Thiol protease. Key protease responsible for the removal of the invariant chain from MHC class II molecules. The bond-specificity of this proteinase is in part similar to the specificities of cathepsin L and cathepsin N.

Publication Abstract from PubMed

A pyridazin-4-one fragment 4 (hCatS IC(50)=170 microM) discovered through Tethering was modeled into cathepsin S and predicted to overlap in S2 with the tetrahydropyridinepyrazole core of a previously disclosed series of CatS inhibitors. This fragment served as a template to design pyridazin-3-one 12 (hCatS IC(50)=430 nM), which also incorporates P3 and P5 binding elements. A crystal structure of 12 bound to Cys25Ser CatS led to the synthesis of the potent diazinone isomers 22 (hCatS IC(50)=60 nM) and 27 (hCatS IC(50)=40 nM).
