Cloning, expression, purification and characterization of a DsbA-like protein from Wolbachia pipientis

Crystallization and preliminary diffraction analysis of a DsbA homologue from Wolbachia pipientis.

alpha-DsbA1 is one of two DsbA homologues encoded by the Gram-negative alpha-proteobacterium Wolbachia pipientis, an endosymbiont that can behave as a reproductive parasite in insects and as a mutualist in medically important filarial nematodes. The alpha-DsbA1 protein is thought to be important for the folding and secretion of Wolbachia proteins involved in the induction of reproductive distor...

Cloning, Expression, and Purification of a GDSL-like Lipase/Acylhydrolase from a Native Lipase-Producing Bacterium, Lactobacillus fermentum

Background: Lipase enzymes are of great importance in various industries. Currently, extensive efforts have been focused on exploring new lipase producer microorganism as well as genetic and protein engineering of available lipases to improve their functional features. Methods: For screening lipase-producing lactobacilli, isolated strains were inoculated onto tributyrin agar plates. Molecular ...

Wolbachia pipientis Bacterial Endosymbiont Encoding the Major Surface Protein of the Cloning and Characterization of a Gene

Cloning and characterization of a gene encoding the major surface protein of the bacterial endosymbiont Wolbachia pipientis.

The maternally inherited intracellular symbiont Wolbachia pipientis is well known for inducing a variety of reproductive abnormalities in the diverse arthropod hosts it infects. It has been implicated in causing cytoplasmic incompatibility, parthenogenesis, and the feminization of genetic males in different hosts. The molecular mechanisms by which this fastidious intracellular bacterium causes ...

Culture and phenotypic characterization of a Wolbachia pipientis isolate.

The recent isolation of Wolbachia pipientis in the continuous cell line Aa23, established from eggs of a strain of the Asian tiger mosquito Aedes albopictus, allowed us to perform extensive characterization of the isolate. Bacterial growth could be obtained in C6/36, another A. albopictus cell line, at 28 degrees C and in a human embryonic lung fibroblast monolayer at 28 and 37 degrees C, confi...
