Toward understanding the function of the universally conserved GTPase HflX from Escherichia coli: a kinetic approach.

15 Nov 2009 Protein synthesis is a highly conserved process in all living cells involving several members of the translation factor (TRAFAC) class of P-loop GTPases, which play essential roles during translation. The universally conserved GTPase HflX has ... Read more...

A complex between biotin synthase and the iron-sulfur cluster assembly chaperone HscA that enhances in vivo cluster assembly.

15 Nov 2009 Biotin synthase (BioB) is an iron-sulfur enzyme that catalyzes the last step in biotin biosynthesis, the insertion of sulfur between the C6 and C9 atoms of dethiobiotin to complete the thiophane ring of biotin. Recent in vitro experiments suggest ... Read more...

The SufBCD Fe-S scaffold complex interacts with SufA for Fe-S cluster transfer.

8 Nov 2009 Iron-sulfur clusters are key iron cofactors in biological pathways ranging from nitrogen fixation to respiration. Because of the toxicity of ferrous iron and sulfide to the cell, in vivo Fe-S cluster assembly transpires via multiprotein biosynthetic ... Read more...

Technical information about 'Escherichia coli'

Definition: A species of gram-negative, facultatively anaerobic, rod-shaped bacteria (GRAM-NEGATIVE FACULTATIVELY ANAEROBIC RODS) commonly found in the lower part of the intestine of warm-blooded animals. It is usually nonpathogenic, but some strains are known to produce DIARRHEA and pyogenic infections. Pathogenic strains (virotypes) are classified by their specific pathogenic mechanisms such as toxins (ENTEROTOXIGENIC ESCHERICHIA COLI), etc.
