Function

[PSA_THEAC] Component of the proteasome core, a large protease complex with broad specificity involved in protein degradation. The T.acidophilum proteasome is able to cleave oligopeptides after Tyr, Leu, Phe, and to a lesser extent after Glu and Arg. Thus, displays chymotrypsin-like activity and low level of caspase-like and trypsin-like activities.^[1] [PSB_THEAC] Component of the proteasome core, a large protease complex with broad specificity involved in protein degradation.

Publication Abstract from PubMed

Nearly all single-particle cryo-EM structures resolved to better than 4-A resolution have been determined using 300-keV transmission electron microscopes (TEMs). We demonstrate that it is possible to obtain reconstructions of macromolecular complexes of different sizes to better than 3-A resolution using a 200-keV TEM. These structures are of sufficient quality to unambiguously assign amino acid rotameric conformations and identify ordered water molecules.

Achieving better-than-3-A resolution by single-particle cryo-EM at 200 keV.,Herzik MA Jr, Wu M, Lander GC Nat Methods. 2017 Oct 9. doi: 10.1038/nmeth.4461. PMID:28991891^[3]
