Host FIH-Mediated Asparaginyl Hydroxylation of Translocated Legionella pneumophila Effectors
FIH-mediated post-translational modification through asparaginyl hydroxylation of eukaryotic proteins impacts regulation of protein-protein interaction. We have identified the FIH recognition motif in 11 Legionella pneumophila translocated effectors, YopM of Yersinia, IpaH4.5 of Shigella and an ankyrin protein of Rickettsia. Mass spectrometry analyses of the AnkB and AnkH effectors of L. pneumo...
متن کاملMechanism of Rab1b deactivation by the Legionella pneumophila GAP LepB.
Legionella pneumophila is an intracellularly surviving pathogen that releases about 270 different proteins into the host cell during infection. A set of secreted proteins takes control of the vesicular trafficking regulator Rab1. Legionella LepB inactivates Rab1 by acting as a GTPase-activating protein (GAP). We present the crystal structure of the Rab1b:LepB complex together with a thorough bi...
متن کاملconstruction and validation of the translation teacher competency test and the scale of students’ perceptions of translation teachers
the major purpose of this study was to develop the translation teacher competency test (ttct) and examine its construct and predictive validity. the present study was conducted in two phases: a qualitative phase as well as a quantitative phase. in the first phase of the study, the author attempted to find out the major areas of competency required for an academic translation teacher. the second...

Adaptation of Legionella pneumophila to the host environment: role of protein secretion, effectors and eukaryotic-like proteins.
The intracellular pathogen Legionella pneumophila has evolved sophisticated mechanisms that enable it to subvert host functions, enter, survive and replicate in amoebae or alveolar macrophages, and to finally evade these hosts. Protozoa are essential for the growth of Legionella and the interaction with amoeba seems to be the driving force in the evolution of its pathogenicity. This is reflecte...
