Lipoate-binding proteins and specific lipoate-protein ligases in microbial sulfur oxidation reveal an atpyical role for an old cofactor

open access: yeseLife, 2018
Many Bacteria and Archaea employ the heterodisulfide reductase (Hdr)-like sulfur oxidation pathway. The relevant genes are inevitably associated with genes encoding lipoate-binding proteins (LbpA).

Comparison of certain complexes of modules of generalized fractions and Cech complexes [PDF]

open access: yesarXiv, 2005
We establish an explicit quasi-isomophism of complexes, which is homogeneous in graded situation, from a given Cech complex of modules of generalized fractions.

Tsallis entropy of complex networks [PDF]

open access: yesarXiv, 2015
How complex of the complex networks has attracted many researchers to explore it. The entropy is an useful method to describe the degree of the $complex$ of the complex networks. In this paper, a new method which is based on the Tsallis entropy is proposed to describe the $complex$ of the complex networks.

Extreme anoxia tolerance in crucian carp and goldfish through neofunctionalization of duplicated genes creating a new ethanol-producing pyruvate decarboxylase pathway

open access: yesScientific Reports, 2017
Without oxygen, most vertebrates die within minutes as they cannot meet cellular energy demands with anaerobic metabolism. However, fish of the genus Carassius (crucian carp and goldfish) have evolved a specialized metabolic system that allows them to ...

THE INFLUENCE OF Bacillus subtilis PROTEINS DegU, SinR AND SinIR ON BACITRACIN BIOSYNTHESIS IN Bacillus licheniformis

open access: yesActa Agriculturae Slovenica, 1998
A vast array of natural peptides diverse in their structure that are produced by microorganisms living in different aquatic and terrestrial environments are not gene encoded but are synthetized nonribosomally on peptide synthetases.

Complex almost contact metric structures on complex hypersurfaces in hyperkahler manifolds [PDF]

open access: yesarXiv, 2015
In this paper, we construct complex metric structures on complex hypersurfaces in hyperkahler manifolds. This construction is that in contact geometry.

Trypanosoma brucei: subcellular distribution and organisation of the enzymes of glycolysis [PDF]

open access: yes, 1977
The cellular distribution of eleven Trypanosoma brucei enzymes involved in glucose breakdown has been studied, using the following six methods of cell disruption: saponin, Triton X-100, digitonin, freezing and thawing, and grinding with the abrasives ...

Lysosomal Cathepsin A Plays Significant Role In The Processing Of Endogenous Bioactive Peptides

open access: yesFrontiers in Molecular Biosciences, 2016
Lysosomal serine carboxypeptidase Cathepsin A (CTSA) is a multifunctional enzyme with distinct protective and catalytic function. CTSA that is present in the lysosomal multienzyme complex facilitates correct lysosomal routing, stability and activation of
