In agreement therewith the clone hybridized in Northern blot analyses with a 1.7 kb mRNA species present the in poly A+ mRNA fraction of both dark grown and greened primary leaves of barley. The nucleotide sequence of the barley clone reveals 75% identity to the Phaseolus vulgaris and Pisum sativum clones encoding chloroplastic glutamine synthetase, while only 69% identity is observed in comparisons with the clones specifying the cytosolic isozymes. At the amino acid level 85% identity is found between the deduced barley glutamine synthetase sequence and that of the corresponding chloroplastic isoenzymes from bean and pea. The chloroplastic glutamine synthetases contain cysteins in the putative ATP and and substrate binding sites. In the cytosolic forms these positions are occupied by alanine residues.","PeriodicalId":9616,"journal":{"name":"Carlsberg Research Communications","volume":"54 1","pages":"1-9"},"PeriodicalIF":0.0,"publicationDate":"1989-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1007/BF02910467","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"13619373","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The beta-glucanase hybrid enzyme 1 (H1) contains the 107 amino-terminal residues of mature B. amyloliquefaciens beta-glucanase and the 107 carboxyl-terminal amino acid residues of B. macerans beta-glucanase. The reciprocal beta-glucanase hybrid enzyme 2 (H2) consists of the 105 amino-terminal residues from the B. macerans enzyme and the carboxyl-terminal 107 amino acids from B. amyloliquefaciens. The biochemical properties of the two hybrid enzymes differ significantly from each other as well as from both parental beta-glucanases. Hybrid beta-glucanase H1 exhibits increased thermostability in comparison to other beta-glucanases, especially in an acidic environment. This hybrid enzyme has maximum activity between pH 5.6 and 6.6, whereas the pH-optimum for enzymatic activity of B. amyloliquefaciens beta-glucanase was found to be at pH 6 to 7 and for B. macerans at pH 6.0 to 7.5. Hybrid enzyme 1 being more heat stable than both parental enzymes represents a case of intragenic heterosis. Hybrid beta-glucanase 2 (H2) was found to be more thermolabile than the naturally occurring beta-glucanases it was derived from and the pH-optimum for enzymatic activity was determined to be between pH 7 and pH 8.","PeriodicalId":9616,"journal":{"name":"Carlsberg Research Communications","volume":"54 2","pages":"41-54"},"PeriodicalIF":0.0,"publicationDate":"1989-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1007/BF02907584","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"13816263","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
