Complete chloroplast genome of the marine eelgrass (Zosteraceae, Plantae) from Monterey, California.

We present the complete chloroplast genome of the eelgrass from Monterey, California. The genome is circular and 144,675  bp in length. It consists of 82 protein-coding, 31 transfer RNA, and 8 ribosomal RNA genes and is 99.

Characterization and primary structures of DNA-binding HU-type proteins from Rhizobiaceae.

The DNA-binding HU-type proteins from several species of Rhizobiaceae including Rhizobium meliloti, two strains of Rhizobium leguminosarum with highly different phenotypic characters and Agrobacterium tumefaciens, were characterized and their amino acid sequences were determined. HU-type proteins isolated from R. leguminosarum L18 and A.

Comparative study of the DNA-binding HU-type proteins from slow growing and fast growing strains of Rhizobiaceae.

The DNA-binding HU-type proteins have been isolated from two very different strains of Rhizobiaceae : Agrobacterium tumefaciens and Rhizobium japonicum. These proteins have been called HAt and HRj respectively. Their electrophoretic mobility on polyacrylamide gel, amino acid composition and crossed immunoreactivity have been compared to that of the homologous protein isolated from Rhizobium meliloti: the protein HRm .

Primary structure of the DNA-binding protein HRm from Rhizobium meliloti.

The amino acid sequence of protein HRm, a DNA-binding HU-type protein of 90 residues (Mr 9303), isolated from Rhizobium meliloti, has been established from automated sequence analysis of the protein and from structural data provided by peptides derived from cleavage of the protein at arginine and aspartic acid residues. The comparison of the primary structure of protein HRm with that of other HU-type proteins shows that two short sequences, of 7 and 6 residues respectively, located in the median part of the molecule, appear highly conserved and may be important in the function of the protein.
