Autor: Piotr Gornicki, J DiMaio, Robert Haselkorn, L. A. Scappino, Jan Podkowiński, E Ward

Publikováno v: Proceedings of the National Academy of Sciences. 91:6860-6864

cDNA fragments encoding part of wheat (Triticum aestivum) acetyl-CoA carboxylase (ACC; EC 6.4.1.2) were cloned by PCR using primers based on the alignment of several biotin-dependent carboxylases. A set of overlapping clones encoding the entire wheat

Genes for two subunits of acetyl coenzyme A carboxylase of Anabaena sp. strain PCC 7120: biotin carboxylase and biotin carboxyl carrier protein

Autor: P Gornicki, L A Scappino, Robert Haselkorn

Publikováno v: Journal of Bacteriology. 175:5268-5272

Genes for two subunits of acetyl-coenzyme A carboxylase, biotin carboxylase and biotin carboxyl carrier protein, have been cloned from Anabaena sp. strain PCC 7120. The two proteins are 181 and 447 amino acids long and show 40 and 57% identity to the

The patA gene product, which contains a region similar to CheY of Escherichia coli, controls heterocyst pattern formation in the cyanobacterium Anabaena 7120

Autor: Jihong Liang, Robert Haselkorn, L. A. Scappino

Publikováno v: Proceedings of the National Academy of Sciences. 89:5655-5659

In Anabaena 7120, heterocysts (cells specialized for nitrogen fixation) develop at the ends of filaments and at intervals within each filament. We have isolated a mutant Anabaena strain that develops heterocysts mostly at the ends of filaments. This

Suppression of heterocyst differentiation in Anabaena PCC 7120 by a cosmid carrying wild-type genes encoding enzymes for fatty acid synthesis

Autor: C C, Bauer, K S, Ramaswamy, S, Endley, L A, Scappino, J W, Golden, R, Haselkorn

Publikováno v: FEMS microbiology letters. 151(1)

A cosmid containing a wild-type Anabaena PCC 7120 DNA fragment was found to suppress heterocyst differentiation, creating a Het phenotype in an otherwise wild-type strain. Curing of the cosmid restored the full wild-type Het+ Nif+ phenotype. The cosm

Growth of the cyanobacterium Anabaena on molecular nitrogen: NifJ is required when iron is limited

Autor: Robert Haselkorn, Christopher C. Bauer, L. A. Scappino

Publikováno v: Proceedings of the National Academy of Sciences of the United States of America. 90(19)

The nifJ gene of Klebsiella pneumoniae encodes an oxidoreductase required for the transfer of electrons from pyruvate to flavodoxin, which reduces nitrogenase. The nifJ gene of Anabaena 7120, isolated from a cosmid bank, was found to contain an open

The patB gene product, required for growth of the cyanobacterium Anabaena sp. strain PCC 7120 under nitrogen-limiting conditions, contains ferredoxin and helix-turn-helix domains

Autor: L A Scappino, Robert Haselkorn, J Liang

Publikováno v: Journal of bacteriology. 175(6)

A mutant of Anabaena sp. strain PCC 7120, called PAT-2, that grows poorly under nitrogen-fixing conditions, has been isolated. The heterocysts of the mutant strain develop much more slowly than those of the wild type and are spaced more closely in an
