'''The structure of thioredoxin from S. coelicolor'''<br />


==Overview==
==The structure of thioredoxin from S. coelicolor==
Thioredoxins are ubiquitous proteins that serve as reducing agents and, general protein disulfide reductases. In turn, they are reduced by, electrons obtained from the NADPH-containing thioredoxin reductase., Thioredoxins have been isolated and characterized from a large number of, organisms. The Gram-positive bacterium Streptomyces coelicolor contains, three thioredoxins that are involved in unknown biological processes. trxA, from S. coelicolor was cloned and expressed in Escherichia coli and the, protein purified and crystallized using the hanging-drop method of vapour, diffusion. The crystal structure of thioredoxin A has been determined at, 1.5 A resolution using a synchrotron-radiation source. The protein reveals, a thioredoxin-like fold with a typical CXXC active site. The crystal, exhibits the symmetry of space group P2(1)2(1)2, with unit-cell parameters, a = 43.6, b = 71.8, c = 33.2 A.

== Function ==
[https://www.uniprot.org/uniprot/THIO1_STRCO THIO1_STRCO] Component of the thioredoxin-thioredoxin reductase system. Participates in various redox reactions through the reversible oxidation of its active center dithiol to a disulfide and catalyzes dithiol-disulfide exchange reactions. Stimulates complex formation between sigma factor SigR and its cognate anti-sigma factor RsrA probably by reducing RsrA.<ref>PMID:10428967</ref>
