Cyanobacteria Nitrogen control NtcA gene Synechococcus sp. Genética Bioquímica y Biología Molecular |
| Descripción: |
The ntcA gene from Synechococcus sp. strain PCC 7942 encodes a regulatory protein which is required for the expression of all of the genes known to be subject to repression by ammonium in that cyanobacterium. Homologs to ntcA have now been cloned by hybridization from the cyanobacteria Synechocystis sp. strain PCC 6803 and Anabaena sp. strain PCC 7120. Sequence analysis has shown that these ntcA genes would encode polypeptides strongly similar (77 to 79% identity) to the Synechococcus NtcA protein. Sequences hybridizing to ntcA have been detected in the genomes of nine other cyanobacteria that were tested, including strains of the genera Anabaena, Calothrix, Fischerella, Nostoc, Pseudoanabaena, Synechococcus, and Synechocystis. This work was supported by grant B1089-0527 from Comisión Interministerial de Ciencia y Tecnología, by grant PB90-0114 from Dirección General de Investigación Científica y Técnica, and by Junta de Andalucía, Spain. J.E.F. was the recipient of a fellowship from Fundación Cámara Urzaiz-Universidad de Sevilla, Seville, Spain. |
