Strong and weak hydrogen bonds in sm/lsm oligomeric assemblies: a comparison of intra- and interchain interaction
(Inst Materials Physics, Bucharest, 2013)
The Sm and Sm-like (LSm) proteins are a widespread protein family with members in all kingdoms of life. Sm proteins form complexes engaging in various RNA-processing events. Sm proteins do form and act as oligomeric ...
Changes in the phytoplankton community and dominance of Cylindrospermopsis raciborskii (Wolosz.) Subba Raju in a temperate lowland river (Ponjavica, Serbia)
(Springer, Dordrecht, 2013)
Species composition and seasonal succession of phytoplankton were analyzed in a lowland river located in South Banat (Ponjavica, Serbia). As a result of human activity, a network of irrigation channels was built on the ...
