The effect of pH upon the equilibria of catalase compounds.
In the preceding study of the effect of pH upon catalase activity (l), the heme-linked hydroxyl group of Agner and Theorell (2) was not found to be necessary for the enzymatic activity, and we have therefore reinvestigated the experimental evidence for this heme linkage from both equilibrium and kinetic studies. And since many of our views of the heme linkages of catalase are based upon analogi...
متن کاملEffect of pH upon the activity of cefoxitin.
Cefoxitin is a new semisynthetic cephamycin antibiotic, effective against gram-positive and gram-negative bacteria. It is of particular interest because of its activity against cephalosporinresistant strains of Escherichia coli, indole-positive Proteus, Klebsiella and Serratia6) and because of its high resistance to hydrolysis by /J-lactamases3). Antibacterial activities of penicillins and ceph...
متن کاملInfluence of pH on the thyroxine effect upon succinoxidase system.
There have been many conflicting results concerning the in vitro effect of thyroxine upon respiratory enzyme systems (Barker, 1951). With regard to the succinoxidase system, Gemmill (1952) and Radsma et al.(1954) showed that thyroxine augmented the enzyme activity in vitro, while, in contrast to such results, McShan et al.(1947) reported inhibitory effect of the hormone, and furthermore, Smith ...
متن کاملFinite Groups of Seitz Type
We show that a useful condition of Seitz on finite groups of Lie type over fields of order q > 4 is often satisfied when q is 2 or 3. We also observe that various consequences of the Seitz condition, established by Seitz and Cline, Parshall, and Scott when q > 4, also hold when q is 3 or 4. In this paper we explore a certain property shared by most finite groups of Lie type first exploited by S...
متن کاملResidue Symbols and Jantzen-Seitz Partitions
Jantzen-Seitz partitions are those p-regular partitions of n which label p-modular irreducible representations of the symmetric group S n which remain irreducible when restricted to S n?1 ; they have recently also been found to be important for certain exactly solvable models in statistical mechanics. In this article we study their combinatorial properties via a detailed analysis of their resid...
