The analysis of the restriction site polymorphism in the repeated sequences in the genomic DNA of the industrially used Saccharomyces Cerevisiae Strains
İzgü, Kadri Fatih; Altınbay, Demet (1995-01-01)
S. cerevisiae BSP-1, BSP-2, BSP-3 and BSP-4 are industrially used baking strains that have same phenotypes, but claimed to be different strains by the industry due to variations in their fermentation activities in dough. In the present study, we have analyzed the rDNA sequences, subtelomeric Y’ sequences and retrotransposon Tyl that are highly repeated in the genomic DNA of the yeast S. cerevisiae. As these three types of repeats have different sequence arrangements in different strains of S. cerevisiae, th...
The effect of cysteine-43 mutation on thermostability and kinetic properties of citrate synthase from Thermoplasma acidophilum
Kocabıyık, Semra; Russel, RJM; Danson, MJ; Hough, DW (Elsevier BV, 1996-07-05)
In this study, we have substituted serine-43 by cysteine in the recombinant citrate synthase from a moderately thermophilic Archaeon Thermoplasma acidophilum, for site-specific attachment of labels and have investigated the effects of this mutation on the biochemical properties and thermal stability of the enzyme. Both wild-type and the mutant enzymes were purified to homogenity using affinity chromatography on Matrex Gel Red A. The mutant Thermoplasma citrate synthase is very similar to wild-type citrate s...
A QSAR study of the biological activities of some benzimidazoles and imidazopyridines against Bacillus subtilis
Ertepınar, Hamide; Gök, Yaşar; Geban, Ömer; Özden, Seçkin (1995-04-01)
A set of benzimidazole (I) and imidazopyridine (II) derivatives that have previously been tested for their antibacterial activities against Bacillus subtilis were analyzed using the quantitative structure-activity relationship (QSAR) method. The activity contributions for structural and substituent effects were determined from the correlation equations, which were derived using all possible combination and stepwise regression techniques. The best equation was chosen among the other equations by considering ...
Comparative analysis of product and by-product distributions in defined and complex media in serine alkaline protease production by recombinant Basillus subtilis
Oktar, Ceren; Çalık, Pınar; Department of Chemical Engineering (2003)
In this study, firstly the effects of aspartic acid group amino acids -which were reported to be the potential bottleneck in serine alkaline protease (SAP) synthesis- on SAP production were investigated by substituting at a concentration range of 0-15 mM by using recombinant Bacillus subtilis carrying pHV1434::subC gene. All aspartic acid group amino acids except threonine inhibited SAP activity when CAA= 2.5 mM. The highest SAP activities with asparagine, aspartic acid, lysine, threonine, isoleucine and me...
The use of pyrolysis mass spectrometry to investigate polymerization and degradation processes of methyl amine-based benzoxazine
Bagherifam, Shahla; Uyar, Tamer; Ishida, Hatsuo; Hacaloğlu, Jale (2010-06-01)
In this study, direct pyrolysis mass spectrometry, DP-MS, was applied to investigate curing and polymerization mechanisms of phenol and methyl amine-based benzoxazine monomer, and thermal decomposition and crosslinking characteristics of the corresponding polybenzoxazine. The results indicated opposing polymerization reaction routes besides the generally accepted one. The cleavage of C-O bonds of the oxazine rings either followed by transformation into a polymer constituting ortho or para substituted phenol...
