چکیده
The Escherichia coli lacZ ochre mutant strain U118 was converted to an amber mutant and suppressed with supF, which inserts tyrosine. Enzymatically active beta-galactosidase was isolated. It contained tyrosine at residue number 17 instead of glutamic acid as in wild type.

In some people the inadequate amount of Beta-galactosidase enzyme, in layer of villous epithelium of the small intestine, causes the disorder of lactose intolerance. This examination was done to observe the existence of Beta-galactosidase enzyme that is produced by separated Lactobacillus from samples of dairy products (milk and cheese). Materials and Methods: Pasteurized and local...
متن کاملPRODUCTION OF BETA-GALACTOSIDASE IN SUBMERGED MEDIA BY ASPERGILLUS ORYZAE, PTCC 5 163
Different compositions of liquid media were used for their efficacy in the production of beta-galactosidase by Aspergillus oryzae in submerged fermentation. Enzyme production was improved by switching from lactose-based media to soybean meal- and wheat bran-based media. Further improvement was made when the soybean meal medium was supplemented with sodium nitrate and magnesium sulfate. Res...
متن کاملIdentification of a Rare Synonymous Beta Globin Mutation, HBB:c.180G>A codon 59 (G>A) in an Iranian Patient
Beta thalassemia is the most common autosomal recessive disorder. The present study reports a rare β globin gene mutation, HBB: c.180G>A: codon 59 (AAG/AAA), in a patient from Gilan province, northern Iran. Nucleotide sequencing of amplified DNA belonging to a 35 years old man presenting mild hypochromia revealed a synonymous mutation due to a G>A conversion at the third position of codon 59 o...
متن کاملCharacterization of novel beta-galactosidase activity that contributes to glycoprotein degradation and virulence in Streptococcus pneumoniae.
The pneumococcus obtains its energy from the metabolism of host glycosides. Therefore, efficient degradation of host glycoproteins is integral to pneumococcal virulence. In search of novel pneumococcal glycosidases, we characterized the Streptococcus pneumoniae strain D39 protein encoded by SPD_0065 and found that this gene encodes a beta-galactosidase. The SPD_0065 recombinant protein released...
متن کاملA Single Point Mutation within the Coding Sequence of Cholera Toxin B Subunit Will Increase Its Expression Yield
Background: Cholera toxin B subunit (CTB) has been extensively considered as an immunogenic and adjuvant protein, but its yield of expression is not satisfactory in many studies. The aim of this study was to compare the expression of native and mutant recombinant CTB (rCTB) in pQE vector. Methods: ctxB fragment from Vibrio cholerae O1 ATCC14035 containing the substitution of mutant ctxB for ami...
