Heterologous expression of xeg1 in yeast shows specificity towards xyloglucan. Enzyme activity on barley β-glucan, HE-cellulose, pachyman and xyloglucan after heterologous gene expression of xeg1 from fungus gardens of Acromyrmex echinatior in yeast. Tested samples are, from the top and clock-wise, empty InvSC (marked green to simplify the identification of samples after incubation), InvSC-pYES2 from glucose medium, InvSC-pYES2 from galactose medium, InvSC-pYES2-xeg1 from glucose medium and InvSC-pYES2-xeg1 from galactose medium. No activity could be detected for any of the samples except for the activated (gal+) InvSC-pYES2-xeg1, which confirmed that Xeg1 is a xyloglucanase
