“…These findings indicate that -Gal-A, -Gal-B, -Gal-C, and -Gal-D are undoubtedly monomeric proteins, although most bacterial -galactosidases reported to date are multimeric, except for that from Streptococcus mitis. 31) -Galactosidases from L. reuteri, 15) Enterobacter agglomerans B1, 20) and L. plantarum WCFS 30) are dimeric, those from B. adolescentis DSM20083, 14) B. infantis HL96, 28) and E. coli, 58) tetrameric, and that from B. bifidum NCIMB41171 22,25) is hexameric. Some of the biochemical characteristics determined for purified -Gal-A, -Gal-B, -Gal-C, and -Gal-D are summarized in Table 1.…”

“…[8][9][10][11] Because of this, a number of studies have reported attempts to isolate a -galactosidase with high transgalactosylation activity from various microorganisms, [4][5][6][7][8] including Bacillus circulans, 12,13) Bifidobacterium adolescentis, 14) Lactobacillus reuteri, 15,16) and others. [17][18][19][20] Furthermore, the genes that encode -galactosidases from bacteria, including B. circulans, 21) Bifidobacterium bifidum [22][23][24][25] / Bifidobacterium infantis, 22,[26][27][28] L. reuteri, 29) L. plantarum, 30) and others, 20,31) have been cloned and sequenced, and the enzymes have been overexpressed in heterologous cells.…”

“…[1][2][3][4] Hence a number of attempts to isolate -galactosidases with high transgalactosylation activities from various microorganisms have been reported, [5][6][7][8][9][10][11][12][13] and genes that encode -galactosidases, [13][14][15][16][17][18][19][20][21][22][23][24] including those of B. circulans ATCC 31382, 13,24) have been cloned. However, the lack of a crystal structure as well as a lack of knowledge of the multimeric and monomeric structures of a number of high molecular weight -galactosidases, except for Escherichia coli -galactosidase, 25) has been a drawback to developing an understanding of the mechanism of transgalactosylation.…”

“…A penészgombák mellett az élesztőgombák is termelnek nagy mennyiségben béta-galaktozidáz enzimet, amelyet széles körben alkalmaznak az élelmiszergyártásban. Az élesztők és a baktériumok által termelt enzimek intracellulárisak [Hung-Lee et al, 2002;Hinz et al, 2004;Hsu et al, 2006;Iqbal et al, 2010;Rhimi et al, 2009;Numanoğlu & Sungur 2004], míg a penészgombák által termeltek jelentős része extracelluláris [Freitas et al, 2011;Manzanares et al, 1998;Nagy et al, 2001]. …”

“…A szakirodalomban fellelhető béta-galaktozidáz enzim stabilitás eredményeit 16. táblázatban foglaltam össze. Számos kísérletben egy meghatározott hőmérsékleten vagy pH-n vizsgálták az enzim stabilitását és adták meg a kezdeti aktivitáshoz képest megmaradt aktivitást százalékosan [Hsu et al, 2006, Iqbal et al, 2010, Zárate et al, 2002, míg a mások a félélet idővel jellemzik azt [Hinz et al, 2004, Rhimi et al, 2009. Talán ez utóbbi meghatározással összehasonlíthatóbbá válnak az adatok.…”
