    Abstract: The invention relates to a novel purified isozyme of an autoclavable superoxide dismutase extracted from the plant Potentilla atrosanguinea Lodd. Var. orgyrophylla, said isozyme having the following characteristics, O2− scavenging activity remains same before and after autoclaving; scavenges O2− from sub-zero temperature of −20° C. to high temperature of +80° C.; O2− scavenging activity at 25° C. for 30 days without adding any stabilizing agent such as polyols or sugars; O2− scavenging activity in the presence of saline (0.9% sodium chloride) to 61.8% of the control (without 0.9% sodium chloride), stable at 4° C. for at least 8 months; contamination free and infection free from any living micro- and/or macro-organism after autoclaving; possesses temperature optima at 0° C.; possesses a molecular weight of 33 kD under non-denaturating conditions; possesses a molecular weight of 36 kD under denaturating conditions; has clear peaks in UV range at 268 and 275 nm; has an enzyme turnover number of 19.53×104% per nmol per min at 0° C.; and requires Cu/Zn as a co-factor, method for the preparation of the purified isozyme of autoclavable superoxide dismutase and formulations containing the said autoclavable superoxide dismutase.

    Abstract: CSBP/p38 is a MAP kinase that is activated in response to stress, endotoxin, interleukin 1 and tumor necrosis factor. Using a catalytically inactive mutant (D168A) of human CSBP2 as the bait in a yeast two-hybrid screen, a kinase has been cloned which shares ˜70% amino acid identity to MAPKAP kinase-2, and thus was designated MAPKAP kinase-3. The binding of CSBP to MAPKAP kinase 3 was confirmed in vitro by the precipitation of epitope-tagged CSBP1, CSBP2 and CSBP2(D168A) and endogenous CSBP from mammalian cells by a bacterially-expressed GST-MAPKAP kinase-3 fusion protein and in vivo by co-precipitation of the epitope-tagged proteins co-expressed in HeLa cells. MAPKAP kinase-3 was phosphorylated by both CSBP1 and CSBP2, and was then able to phosphorylate HSP27 in vitro. Treatment of HeLa cells with sorbitol or TNF resulted in activation of CSBP and MAPKAP kinase-3 and activation of MAPKAP kinase-3 could be blocked by preincubation of cells with 4-(4-Fluorophenyl)-2-(4-methylsulfinylphenyl)-5-4-pyridyl)-1H-imidazole, a specific inhibitor of CSBP kinase activity. These data suggest that MAPKAP kinase-3 is activated by stress and cytokines and is a novel substrate of CSBP both in vitro and in vivo. The use of MAPKAP kinase-3 in screens for the identification of pharmaceutically active compounds is disclosed.
