The chloroplast genome exists in multimeric forms.
Chloroplast DNA conformation was analyzed by pulse-field gel electrophoresis. We found that spinach leaf chloroplast DNA molecules exist in at least four distinct forms with the apparent molecular weights of monomer, dimer, trimer, and tetramer. Two-dimensional gel analysis of DNA after UV nicking and in the presence of ethidium bromide indicates that they are not isomers that differ in superhe...
متن کاملThe Bryopsis hypnoides Plastid Genome: Multimeric Forms and Complete Nucleotide Sequence
BACKGROUND Bryopsis hypnoides Lamouroux is a siphonous green alga, and its extruded protoplasm can aggregate spontaneously in seawater and develop into mature individuals. The chloroplast of B. hypnoides is the biggest organelle in the cell and shows strong autonomy. To better understand this organelle, we sequenced and analyzed the chloroplast genome of this green alga. PRINCIPAL FINDINGS A ...
متن کاملChloroplast ribosomal protein L32 is encoded in the chloroplast genome.
The 50 S subunit of chloroplast ribosomes was prepared from tobacco leaves. The proteins were fractionated and the N-terminal amino acid sequence of a 14 kDa protein was determined. This sequence matches the N-terminal sequence deduced from ORF55 located between ndhF and trnL on the small single-copy region of tobacco chloroplast DNA. The deduced protein shows homology to E. coli and B. stearot...
متن کاملHuntingtin Exists as Multiple Splice Forms in Human Brain.
BACKGROUND A CAG repeat expansion in HTT has been known to cause Huntington's disease for over 20 years. The genomic sequence of the 67 exon HTT is clear but few reports have detailed alternative splicing or alternative transcripts. Most eukaryotic genes with multiple exons show alternative splicing that increases the diversity of the transcriptome and proteome: it would be surprising if a gene...
متن کاملBrain-specific polypeptide 1B236 exists in multiple molecular forms.
The COOH-terminal amino acid sequence of the rat brain-specific polypeptide 1B236 was previously deduced from molecular cloning and nucleotide sequence determination of its mRNA and the 1B236 protein shown to exist in the rat brain. The amino acid sequence of 1B236 contained at least three peptide sequences demarcated by pairs of basic amino acids--a structure similar to known neuropeptide and ...
