Most breast and prostate tumors are hormone-dependent, making it possible to use hormone therapy in patients with these tumors. The design of effective endocrine drugs that block the growth of tumors and have no severe side effects is a challenge. Thereupon, synthetic steroids are promising therapeutic drugs for the treatment of diseases such as hormone-dependent breast and prostate cancers. He...
The six domain, 229 kDa HMWP2 subunit of the Yersinia pestis yersiniabactin (Ybt) synthetase has been expressed in soluble, full-length form in E. coli as a C-terminal His8 construct at low growth temperatures and with attenuated induction. All six domains of this nonribosomal peptide synthetase subunit, three phosphopantetheinylatable carrier protein domains (ArCP, PCP1, PCP2), one adenylation...
Although gold is chemically inert as a bulk metal, the landmark discovery that gold nanoparticles can be effective catalysts has opened up new and exciting research opportunities in the field. In recent years, there has been growth in the number of reactions catalyzed by gold complexes [gold(I) and gold(III)], usually as homogeneous catalysts, because they are soft Lewis acids. In addition, alk...
The ability to utilize the iron bound by high-affinity iron-binding proteins in the vertebrate host is an important virulence factor for the marine fish pathogen Vibrio anguillarum. Virulence in septicemic infections is due to the presence of a highly efficient plasmid-encoded iron transport system. AngR, a 110-kDa protein component of this system, appears to play a role in both regulation of t...
