Quality of GNSS Traces from VGI: A Data Cleaning Method Based on Activity Type and User Experience

ISPRS International Journal of Geo-Information, 2020
VGI (Volunteered Geographic Information) refers to spatial data collected, created, and shared voluntarily by users. Georeferenced tracks are one of the most common components of VGI, and, as such, are not free from errors.

SecA, a remarkable nanomachine [PDF]

Cellular and Molecular Life Sciences, 2011
Biological cells harbor a variety of molecular machines that carry out mechanical work at the nanoscale. One of these nanomachines is the bacterial motor protein SecA which translocates secretory proteins through the protein-conducting membrane channel SecYEG.

Energetics of SecA Dimerization [PDF]

Journal of Molecular Biology, 2011
Transport of many proteins to extracytoplasmic locations occurs via the general secretion (Sec) pathway. In Escherichia coli, this pathway is composed of the SecYEG protein-conducting channel and the SecA ATPase. SecA plays a central role in binding the signal peptide region of preproteins, directing preproteins to membrane-bound SecYEG and promoting ...

SecA inhibitors as potential antimicrobial agents: differential actions on SecA-only and SecA-SecYEG protein-conducting channels [PDF]

FEMS Microbiology Letters, 2018
Abstract Sec-dependent protein translocation is an essential process in bacteria. SecA is a key component of the translocation machinery and has multiple domains that interact with various ligands. SecA acts as an ATPase motor to drive the precursor protein/peptide through the SecYEG protein translocation channels.
