lac operon....function of transacetylase

[acab]

Hi Guys,

I'm writing my last lab report for biochem lab and would like to find out the function of the enzyme transacetylase for extra credit (very much needed!). The report is on the lac operon of E. coli.

So, transacetylase is coded by gene A in the lac operon and seems to be involved in breaking down certain sugars. Its function remains unkown, but I was wondering maybe some of you have a good idea about this. I don't seem to find any theories on it.

Thanks a lot.

acetylates b-galactosides?

So, it might acetylate nonmetabolizable b-galactosides, preventing their reentry into the cell, thus assisting in cellular detox?

Thanks Kashue.

Thanks Kashue.

Yes, actually nonmetabolizable pyranosides.

It acetylates lactose to form CoA, but it has not been found to be essential to lactose catabolism

Thanks Kashue and NotJerry!

I just finished typing it. I owe you guys a beer!
