Báo cáo khoa học: Allosteric water and phosphate effects in Hoplosternum littorale hemoglobins pdf

... r ole f or water in d etermining structure and regulating function of proteins is becoming increasingly evident, as water molecules act as allosteric effectors by preferentially binding to a specific ... binding. Although having very different oxygen-binding proper- ties, both Hbs respond to an increase in water activity with an increase on oxygen affinity, indicating preferential...

... degrees of instantiation in LTFS, however, corresponding to long subtyping chains that terminate in ⊥. A more general and useful primitive in a typed language with such chains is suspending until ... suspending until a variable is instantiated, and (2) suspending until two variables are equated or inequated. The latter corresponds exactly to structure-sharing in TFSs, and to sha...
