Heterokaryosis in Neurospora sitophila.
ETEROKARYOSIS has been extensively used as a major tool in formal genetic analysis of both Mendelian and non-Mendelian genes and in establishing gene-enzyme relationships. So far it is the only way to perform genetic anslysis of somatic cells in tissue culture (EPHRUSSI 1965; MINTZ and BAKER 1967). These aspects of heterokaryosis have been reviewed elsewhere ( JINKS 1965; FINCHAM 1966; DAVIS 19...

متن کاملPurification and characterization of potato lectin.
Potato lectin (Solanum tuberosum agglutinin, STA), purified by affinity chromatography on tri-N-acetylchitotriose-Sepharose 6B, has Mr approximately 100,000, as estimated by gel filtration on Sephadex G-150 and is an aggregating system with a monomer Mr = 54,000, as estimated by sedimentation equilibrium analysis. Equilibrium dialysis showed that STA (dimer) has two binding sites for a specific...
متن کاملPurification and characterization of arginase from Neurospora crassa.
We have purified an enzymatically active form of arginase from a wild-type strain of Neurospora crassa to homogeneity. The enzyme has a subunit molecular weight of 38,300 as determined by sodium dodecyl sulfate-polyacrylamide gel electrophoresis. The native protein migrated as a hexamer during gel-filtration chromatography with an apparent molecular weight of 266,000. The enzyme exhibited hyper...
متن کاملPurification and characterization of flavokinase from Neurospora crassa.
The ATP-dependent phosphorylation of riboflavin to FMN by flavokinase is the key step in flavin biosynthesis. Flavokinase has been purified from a fungal source for the first time. The enzyme purified from a cell wall lacking mutant of Neurospora crassa, slime, is a monomer of M(r) 35.5 kDa with maximal activity at alkaline pH and high temperature (55 degrees C). The K(m) for both substrates is...
