Terminal oxidases provide the final step in aerobic respiration by reducing oxygen. The mycobacteria possess two terminal oxidases: a cytochrome c aa3type and a quinol bd type. We previously isolated a bd-type oxidase knockout mutant of Mycobacterium

Spectroscopic analysis of membranes isolated fromMycobacterium smegmatis, along with analysis of its genome, indicates that the cytochromecbranch of its respiratory pathway consists of a modifiedbc1complex that contains two cytochromescin itsc1subuni

Colonies of Mycobacterium smegmatis LR222 on iron-limiting (0.1 μM Fe) minimal medium agar fluoresce under UV light due to the accumulation in the cells of the deferri form of the siderophore mycobactin. Two mutants with little or no fluorescence, d

Many strains of mycobacteria produce two ferric chelating substances that are termed exochelin (an excreted product) and mycobactin (a cell-associated product). These agents may function as iron acquisition siderophores. To examine the genetics of th

The Escherichia coli btuB product is an outer membrane protein that mediates the TonB-coupled active transport of cobalamins and the uptake of the E colicins and bacteriophage BF23. The roles of various segments of the BtuB protein in its function or

The Escherichia coli btuB gene product is an outer membrane protein required for the active transport of vitamin B12 and other cobalamins. Synthesis of BtuB is repressed when cells are grown in the presence of cobalamins. Mapping of the 5' end of the

Synthesis of the btuB-encoded outer membrane receptor for vitamin B12 and the metE-encoded homocysteine methyltransferase is repressed by growth of Escherichia coli in the presence of vitamin B12. The regulation by vitamin B12 of the production of be
