Structure-Guided Recombination Creates an Artificial Family of Cytochromes P450 [PDF]

, 2006
Creating artificial protein families affords new opportunities to explore the determinants of structure and biological function free from many of the constraints of natural selection.

Metabolic engineering of cucurbitacins in Cucurbita pepo hairy roots

Frontiers in Plant Science, 2022
In this paper we show that metabolic engineering in Cucurbita pepo hairy roots can be used to both effectively increase and modify cucurbitacins. Cucurbitacins are highly-oxygenated triterpenoids originally described in the Cucurbitaceae family, but have

A cytochrome b561 with ferric reductase activity from the parasitic blood fluke, Schistosoma japonicum. [PDF]

PLoS Neglected Tropical Diseases, 2010
BACKGROUND: Iron has an integral role in numerous cellular reactions and is required by virtually all organisms. In physiological conditions, iron is abundant in a largely insoluble ferric state.

Structure of a bacterial cell surface decaheme electron conduit [PDF]

, 2011
Some bacterial species are able to utilize extracellular mineral forms of iron and manganese as respiratory electron acceptors. In Shewanella oneidensis this involves decaheme cytochromes that are located on the bacterial cell surface at the termini of ...

In situ spectroscopy reveals that microorganisms in different phyla use different electron transfer biomolecules to respire aerobically on soluble iron

Frontiers in Microbiology, 2016
Absorbance spectra were collected on twelve different live microorganisms, representing six phyla, as they respired aerobically on soluble iron at pH 1.5.

H NMR Studies of Eukaryotic Cytochrome c [PDF]

, 1982
H NMR resonance assignments in the spectra of horse, tuna, Neurmpora crassa and Candida krusei cyto-chromes c are described. Assignments have been made using NMR double-resonance techniques in conjunction with electron-exchange experiments, spectral ...

Characterization of Shewanella oneidensis MtrC: a cell-surface decaheme cytochrome involved in respiratory electron transport to extracellular electron acceptors [PDF]

, 2007
MtrC is a decaheme c-type cytochrome associated with the outer cell membrane of Fe(III)-respiring species of the Shewanella genus. It is proposed to play a role in anaerobic respiration by mediating electron transfer to extracellular mineral oxides that ...
