  • Title: Characterization of the Acinetobacter baumannii Fur regulator: cloning and sequencing of the fur homolog gene.
    Author: Daniel C, Haentjens S, Bissinger MC, Courcol RJ.
    Journal: FEMS Microbiol Lett; 1999 Jan 01; 170(1):199-209. PubMed ID: 9919669.
    Abstract:
    Growth kinetics, siderophore activity and iron-regulated bacterial proteins of Acinetobacter baumannii BM2580 were studied in iron-restricted and iron-supplemented chemically defined media. Iron-regulated outer membrane proteins of 75 kDa and 80 kDa were expressed under iron-restricted conditions. Cloning and sequencing of the complete iron-uptake regulatory (fur) gene from A. baumannii BM2580 is reported for the first time. This gene is preceded by a single autoregulated promoter whose -10 region overlaps the Fur binding site. The open reading frame identified encodes a polypeptide consisting of 145 amino acids. The fur gene is followed by a divergent open reading frame coding for the C-terminus of a putative PilU protein. Sequence analysis indicates that the Fur protein of A. baumannii was 63% identical to the Escherichia coli Fur protein.
