Purification and characterization of the assimilatory nitrate reductase of Azotobacter vinelandii.
1. A soluble reduced Methyl Viologen-dependent assimilatory nitrate reductase from Azotobacter vinelandii strain UW136 grown aerobically on nitrate was purified to homogeneity by the criteria of nitrate reductase activity staining, and coincidence of a Coomassie Blue-staining protein band on polyacrylamide gels run under non-denaturing conditions. The specific activity was 3 mumol of NO2- forme...
متن کاملPurification and Characterization of NafY (Apodinitrogenase Subunit) from Azotobacter vinelandii*
The formation of an active dinitrogenase requires the synthesis and the insertion of the iron-molybdenum cofactor (FeMo-co) into a presynthesized apodinitrogenase. In Azotobacter vinelandii, NafY (also known as protein) has been proposed to be a FeMo-co insertase because of its ability to bind FeMo-co and apodinitrogenase. Here we report the purification and biochemical characterization of NafY...
متن کاملAn NADH-Dependent Acetoacetyl-CoA Reductase from Euglena gracilis: Purification and Characterization, Including Inhibition by Acyl Carrier Protein.
An NADH-dependent acetoacetyl-CoA reductase from Euglena gracilis variety bacillaris was extensively purified and characterized. Two different isoelectric forms of the reductase with identical characteristics otherwise were found. The reductase was noncompetitively inhibited by acyl carrier protein, K(i) 5.6 micromolar at pH 5.4; this inhibition decreased with increasing pH or ionic strength. C...
متن کاملa study on the design of bio-ethanol process from date wastes of sistan and baluchistan province
اتانول کاربردهای متنوعی در صنایع لاستیک سازی، رنگسازی، حلالها ومکمل سوخت خودرو دارد. اتانول برخلاف نفت از جمله مواد تجدیدپذیر محسوب می شود که مشکلات زیست محیطی و آلودگی نیز ایجاد نمی کند. استفاده از اتانول به عنوان مکمل سوختخودروها از جمله مهمترین مصارف صنعتی این ماده بشمار می رود. با توجه به این موضوع تحقیق و توسعه در زمینه تولید اتانول با درجه خلوص بالا در سطح جهان، و نه تنها در کشور های پیشر...
Purification and characterization of the selenate reductase from Thauera selenatis.
Thauera selenatis is one of two isolated bacterial species that can obtain energy by respiring anaerobically with selenate as the terminal electron acceptor. The reduction of selenate to selenite is catalyzed by a selenate reductase, previously shown to be located in the periplasmic space of the cell. This study describes the purification of the enzyme from T. selenatis grown anaerobically with...
