The Escherichia coli Protein YfeX Functions as a Porphyrinogen Oxidase, Not a Heme Dechelatase

open access: yesmBio, 2011
The protein YfeX from Escherichia coli has been proposed to be essential for the process of iron removal from heme by carrying out a dechelation of heme without cleavage of the porphyrin macrocycle.

Cathodic bacterial community structure applying the different co-substrates for reductive decolorization of Alizarin Yellow R [PDF]

open access: yes
Selective enrichment of cathodic bacterial community was investigated during reductive decolorization of AYR fedding with glucose or acetate as co-substrates in biocathode. A clear distinction of phylotype structures were observed between glucose-fed and

The secretion of Pseudomonas unconventional peroxidase facilitates extracellular carbon acquisition from heterogeneous lignin

open access: yesCommunications Biology
The secretion of ligninolytic enzyme provides a competitive advantage for microbial survival. These enzymes are commonly transported to the extracellular milieu via signal peptides for the catabolism of lignin, which cannot be translocated through the ...

Production of two novel laccase isoforms by a thermotolerant strain of Pycnoporus sanguineus isolated from an oil-polluted tropical habitat [PDF]

open access: yes, 2008
A thermotolerant and halotolerant strain of Pycnoporus sanguineus was isolated from an oil-polluted site in a tropical area located in Veracruz, Mexico. This strain was able to grow at 47ºC and in culture medium containing 500 mM NaCl.
