Immenschuh S, Vijayan V, Janciauskiene S, Gueler F.
PMID: 28420988
Front Pharmacol. 2017 Apr 04;8:146. doi: 10.3389/fphar.2017.00146. eCollection 2017.

Heme is a complex of iron and the tetrapyrrole protoporphyrin IX with essential functions in aerobic organisms. Heme is the prosthetic group of hemoproteins such as hemoglobin and myoglobin, which are crucial for reversible oxygen binding and transport. By...

In metal-mediated O

Formation of 1-octen-3-ol from Aspergillus flavus conidia is accelerated after disruption of cells independently of Ppo oxygenases, and is not a main cause of inhibition of germination.

PeerJ

Miyamoto K, Murakami T, Kakumyan P, Keller NP, Matsui K.
PMID: 24883255
PeerJ. 2014 May 20;2:e395. doi: 10.7717/peerj.395. eCollection 2014.

Eight-carbon (C8) volatiles, such as 1-octen-3-ol, are ubiquitous among fungi. They are the volatiles critical for aroma and flavor of fungi, and assumed to be signals controlling germination of several fungi. In this study, we found that intact Aspergillus...

Coordinated and Iterative Enzyme Catalysis in Fungal Polyketide Biosynthesis.

ACS catalysis

Hang L, Liu N, Tang Y.
PMID: 28529817
ACS Catal. 2016 Sep 02;6(9):5935-5945. doi: 10.1021/acscatal.6b01559. Epub 2016 Jul 27.

Fungal polyketides are natural products with great chemical diversity that exhibit a wide range of biological activity. This chemical diversity stems from specialized enzymes encoded in the biosynthetic gene cluster responsible for the natural product biosynthesis. Fungal polyketide synthases...

Purification and identification of trichloroethylene induced proteins from Stenotrophomonas maltophilia PM102 by immuno-affinity-chromatography and MALDI-TOF Mass spectrometry.

SpringerPlus

Mukherjee P, Roy P.
PMID: 23741645
Springerplus. 2013 May 07;2(1):207. doi: 10.1186/2193-1801-2-207. Print 2013 Dec.

A novel bacterial isolate capable of growth on trichloroethylene as the sole carbon source was identified as Stenotrophomonas maltophilia PM102 by 16S rDNA sequencing (GenBank Acc.no. JQ797560). Serum was obtained from a rabbit immunized with the total protein extracted...

Mono- and binuclear complexes of iron(II) and iron(III) with an N4O ligand: synthesis, structures and catalytic properties in alkane oxidation.

Dalton transactions (Cambridge, England : 2003)

Li F, Wang M, Ma C, Gao A, Chen H, Sun L.
PMID: 16705341
Dalton Trans. 2006 May 28;(20):2427-34. doi: 10.1039/b516697g. Epub 2006 Mar 15.

Three mononuclear iron complexes and one binuclear iron complex, [Fe(tpoen)Cl].0.5(Fe2OCl6) (1), [Fe(tpoen)Cl]PF6 (2), Fe(tpoen)Cl3 (3) and [[Fe(tpoen)]2(mu-O)](ClO4)4 (4) (tpoen = N-(2-pyridylmethoxyethyl)-N,N-bis(2-pyridylmethyl)amine), were synthesized as functional models of non-heme iron oxygenases. Crystallographic studies revealed that the Fe(II) center of 1...

Caenorhabditis Elegans Mutants Predict Regulation of Fatty Acids and Endocannabinoids by the CYP-35A Gene Family.

Frontiers in pharmacology

Aarnio V, Lehtonen M, Storvik M, Callaway JC, Lakso M, Wong G.

Front Pharmacol. 2011 Mar 18;2:12. doi: 10.3389/fphar.2011.00012. eCollection 2011.

BACKGROUND: Cytochrome P450s (CYPs) are mono-oxygenases that metabolize endogenous compounds, such as fatty acids and lipid signaling molecules, and furthermore have a role in metabolism of xenobiotics. In order to investigate the role of CYP genes in fat metabolism...

Pharmacovigilance: effects of herbal components on human drugs interactions involving cytochrome P450.

Bioinformation

Saxena A, Tripathi KP, Roy S, Khan F, Sharma A.
PMID: 19255634
