Cloning, purification and characterization of the ribosomal protein L11 from E. coli
(Scientific Research Publishing, 2011-04)A high-expression system of L11 was constructed and investigated its interaction with other elements of the ribosome using physicochemical methods. The gene rplK, coding for the protein L11 from the E. coli 50S ribosomal ... -
Codon bias of influenza a viruses and their hosts
(Scientific Research Publishing, 2011-10)The Influenza A virus remains an annual and worldwide health concern due to its fast evolutionary rate. There are two major forms of Influenza evolution: drift, caused by mutations, and shift, which results from the exchange ... -
