To improve security and privacy, we are moving our web pages and services from HTTP to HTTPS. To give users of web services time to transition to HTTPS, we will support separate HTTP and HTTPS services until the end of 2017. From January 2018 most HTTP traffic will be automatically redirected to HTTPS. [more...] View this page in https
A family of eukaryotic and prokaryotic proteins that seem to be mainly
involved in the intake of small peptides with the concomitant uptake of a
proton has been recently characterized [1,2]. Proteins that belong to this
Lactococcus proton-dependent di- and tri-peptide transporter dtpT.

Bacillus subtilis hypothetical protein yclF.
These integral membrane proteins are predicted to comprise twelve
transmembrane regions. As signature patterns, we selected two of the best
conserved regions. The first is a region that includes the end of the second
transmembrane region, a cytoplasmic loop as well as the third transmembrane
region. The second pattern corresponds to the core of the fifth transmembrane
