Abstract:
Here we report the enzymatic characteristics and regulation of expression for two GH36 a- galactosidases. Agu 1 and Aga,'. li'0111 R. gnavus El. Bioinforrnatics analysis of their respective genetic environment showed a different organisation. Aga 1 having a simple organisation while Aga2 is organised as part nf an ()p~wn. They were heterologously expressed in Escherichia coli. puri tied to homogeneity and their biochemical properties and substrate preferences comparatively analysed. The growth pattern (If the strain in minimum media demonstrates a preference tor complex substratcs (melibiose and raffinose) that require the expression of the a-galactosid.rscs for their utilisation and assimilation. Keywords: a-galactosidase. Ruminococcus gnavus E I. characterisation. transglycosylation. regulation. metabolism
