Nitrogenase of Klebsiella pneumoniae
1. Nitrogenase from the facultative anaerobe Klebsiellapneumoniae was resolved into two protein components resembling those obtained from other nitrogen-fixing bacteria. 2. Both proteins were purified to homogeneity as shown by the criteria of disc electrophoresis and ultracentrifugal analysis. 3. The larger component had a mol.wt. of 218000 and contained one Mo atom, 17Fe atoms and 17 acid-lab...

متن کاملSequence Homology between Chloroplast DNAs from Several Higher Plants.
An estimate has been made of the amount of sequence homology present in the chloroplast DNA (ctDNA) of several higher plants by the technique of DNA-DNA hybridization. Approximately 85% of tomato, 60% of spinach, 45% of kale, and 15% of barley ctDNA sequences were found to hybridize with tobacco ctDNA under conditions in which maximum hybridization in homologous reactions reached 85%. All heter...
متن کاملGenes for D-arabinitol and ribitol catabolism from Klebsiella pneumoniae.
The enzymes for catabolism of the pentitols D-arabinitol (Dal) and ribitol (Rbt) and the corresponding genes from Klebsiella pneumoniae (dal and rbt) and Escherichia coli (atl and rtl) have been used intensively in experimental evolutionary studies. Four dal and four rbt genes from the chromosome of K. pneumoniae 1033-5P14 were cloned and sequenced. These genes are clustered in two adjacent but...
