Serine 130 is one of seven residues that form a total of seven hydrogen bonds with the sulfate completely sequestered deep in the cleft between the two lobes of the bilobate sulfate-binding protein from Salmonella typhimurium. This residue has been replaced with Cys, Ala, and Gly by site-directed mutagenesis in an Escherichia coli expression system.(More)
There is disagreement about the association between missing posterior teeth and the presence of temporomandibular disorders (TMD). Here, the purpose was to investigate whether the number of missing posterior teeth, their distribution, age, and gender are associated with TMD. Seven hundred and forty-one individuals, aged 21-60 years, with missing posterior(More)
This paper describes some methods for contention resolution in bulk flow TCP routing in optical IP network through simulation. The various domains such as wavelength, time and space with respect to bulk flow TCP to resolve contention are studied. The results show that the flow based transmission under wavelength domain exhibits only the probability of(More)
