Many studies in vitro have implicated cytochrome oxidase and monoamine oxidase in the metabolism of epinephrine and other cateehol amines (2). However, no evidence for the participation of cytochrome oxidase in the metabolism of epinephrine in viva has been obtained. Furthermore, several investigations have indicated that monoamine oxidase plays only a minor role in the inactivation of epinephr...

Three dinuclear Co complexes [(Co2(H2L)2(OAc)2)] CH3OH (1), [CoCo(H2L)2(OAc)] 2CH3OH H2O (2), and [CoCo(H2L)2(CH3CN)(H2O)]Cl CH3CN 4H2O (3) [H4L is (3,5-di-tert-butyl-2-hydroxybenzylideneamino)-2(hydroxymethyl)propane-1,3-diol] were synthesized and characterized using single crystal X-ray diffraction and other analytical methods. Complex 1 having two Co centres was the only one found to show ca...

Polyphenol oxidase (PPO) (E.C. 1.14.18.1) also known as phenolase, catechol oxidase, catecholase, monophenol oxidase, o-diphenol oxidase and orthophenolase based on their substrate specificity, is widely distributed in plants and fungi (Mayer, 2006; Kaur et al., 2010; Asha et al., 2011; Pawar and Ingle, 2014). PPOs have been purified and characterized from a wide range of plant species and a va...

The enzyme, pyrocatechase, isolated and partially purified from anthranilate-adapted cells of a pseudomonad, was shown to catalyze the oxidative cleavage of the aromatic ring of catechol to cis, cis-muconic acid (1). Subsequently, through the use of 0218 and HsO~~, the two oxygen atoms incorporated across the double bond between the two hydroxyl groups were shown to be derived from atmospheric ...
