The nucleotide sequence of region 2 of the Escherichia coli K5 capsule gene cluster has been determined. This region, essential for the biosynthesis of the K5 polysaccharide, contained four genes, termed kfiA-D. The G + C ratio was 33.4%, which was lower than the typical G + C ratio for E. coli and that of the flanking regions 1 and 3 in the K5 capsule gene(More)
This paper presents a new method for creating microscopic patterns of stretched and oriented molecules of DNA on a surface. Combing of molecules in microchannels (COMMIC), a process by which molecules are deposited and stretched onto a surface by the passage of an air−water interface, creates these patterns. This approach demonstrates that the direction of(More)
