Characterization of Glutamine Synthetase of Roots, Etiolated Cotyledons and Green Leaves from Sinapis alba (L.)
Glutamine synthetase of roots, etiolated cotyledons and green leaves from mustard plants cannot all clearly be separated by DEAE-Sephacel chromatography. However, the enzyme of the roots, etiolated cotyledons and green leaves, respectively, differed in the kinetic properties deter mined in the crude extract. The root enzyme showed a pH-optimum of about 6.9, a Km value of 3 m M for glutamate an...
متن کاملCloning and mapping of the chloroplast DNA sequences for two messenger RNAs from mustard (Sinapis alba L.).
Restriction fragments of chloroplast (cp)DNA from mustard leaves were cloned in E. coli using pBR 322 as the vehicle. Cloned fragments containing the structural sequences for two polypeptides of 56,000 and 35,000 daltons were selected by a mRNA hybridization-translation procedure. The cloned mustard genes are structurally related to chloroplast genes from maize. They hybridize to the maize mRNA...
متن کاملNucleotide sequence of the intergenic spacer and the 18S ribosomal RNA gene from mustard (Sinapis alba).
From a rRNA repeating unit (9.1 kbp) of mustard we have The DNA was sequenced according to the method of Maxam sequenced the first internal transcribed spacer, the 5.8S rRNA and Gilbert gene, and the second internal transcribed spacer [1]. Here, we present the nucleotide sequence of a 5500 bp fragment containing the 3 ' end terminus of the 25S gene (486 bp), the intergenic spacer REFERENCES (32...
متن کاملSequence and expression characteristics of a nuclear-encoded chloroplast sigma factor from mustard (Sinapis alba).
Plant chloroplasts contain transcription factors that functionally resemble bacterial sigma factors. We have cloned the full-length cDNA from mustard (Sinapis alba) for a 53 kDa derived polypeptide that contains similarity to regions 1.2-4.2 of sigma70-type factors. The amino acid sequence at the N-terminus has characteristics of a chloroplast transit peptide. An in vitro synthesized polypeptid...
