  1. Structural Studies on Ferric Uptake Regulator Proteins from Mycobacterium tuberculosis

    Lucarelli, DeboraUniversität Heidelberg

    … transcription of genes involved in iron uptake, transport and storage. Paucity of this metal triggers an extensive response to increase iron acquisition whereas an excess of it can be toxic for the cell. The control of intracellular iron concentration is also linked to other important …

  2. Characterization of Complex Transcriptional Regulation Within the YQJH-YQJI Intergenic Region

    Philipkosky, Katherine

    … systems (Andrews et al 2003, 216). In E. coli, ferric uptake regulator, Fur, regulates the transcription of several genes involved with iron acquisition (Hantke 2001, 172). One of these genes, yqjH, encodes the enzyme YqjH, a putative ferric reductase. Previous studies have shown that yqjH is …

    … and genomic analyses indicate several potential uptake systems and iron-responsive regulators. Transcription of the <i>hbp</i> genes (hemin binding protein genes) is responsive to alterations in available hemin and an HbpA homolog in <i>B. henselae</i> reportedly functions as a hemin receptor in …

    Jokisch, Bettina

    … Eine H. pylori-Mutante, der der zentrale Regulator des Eisenstoffwechsels Fur fehlt, erwies sich als deutlich sensibler gegen den Eisen-vermittelten oxidativen Stress. Mutationen in dem putativen Metallexportsystem HP0971-NccB-CzcA1, bewirkten keine Verstärkung der Me-tall-vermittelten …
