Streptococcal M Protein Extracted by Nonionic Detergent
Streptococcal M proteins are antiphagocytic molecules varying immunologically from type to type while maintaining an identical biological effect. The virulence of the group A streptococcus is directly related to the presence of the M antigens on the cell surface and resistance to infection by these organisms is dependent on the presence of opsonic antibodies directed towards the M molecules. Va...
متن کاملAlkaline phytase activity in nonionic detergent extracts of legume seeds.
Alkaline phytase activity, with a pH optimum of 8, was recovered from detergent extracts of dormant seeds of nine varieties of Phaseolus vulgaris L., Pisum sativum L. var. Early Alaska, and Medicago sativa L. This alkaline phytase of legume seeds was activated by calcium and differed from most seed phytases in its relative insensitivity to inhibition by fluoride.
متن کاملSalt Effects in Free Nonionic Films
value for the enthalpy of adsorption of both CO and NO. A plausible explanation of the correlation observed is as follows. The standard entropy of adsorption is ascribable to the stretch of the cation-carbon (or cation-nitrogen) bond and to two bending modes of CO (or NO). The frequencies involved are usually (see, e.g., ref 19) assumed to parallel the strength of adsorption AaH. As a matter of...
متن کاملOn the thinning of films (I)
We investigate, from a mathematical perspective, the problem of a layer of fluid attracted to a horizontal plate when the layer is in equilibrium with a bulk reservoir. It is assumed that as the temperature varies, the bulk undergoes a continuous phase transition. On the basis of free energetics, this initially causes thinning of the layer but, at lower temperatures, the layer recovers and rebu...
متن کاملEnhanced macrocyclizing activity of the thioesterase from tyrocidine synthetase in presence of nonionic detergent.
Macrocyclization carried out by thioesterase domains of multimodular nonribosomal peptide synthetases (NRPSs) is a key step in the biosynthesis of many biologically active peptides. The thioesterase excised from tyrocidine synthetase is a versatile macrocyclization catalyst and a useful tool for chemoenzymatic synthesis of diverse cyclic peptides. However, its utility is limited by its short li...
