[[http://www.uniprot.org/uniprot/PSA_THEAC 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.<ref>PMID:8999862</ref> [[http://www.uniprot.org/uniprot/PSB_THEAC 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.
