I wish to use lactate dehydrogenase promoter from Lactobacillus acidophillus for heterologous expression of some genes under it in the same species. I saw few papers like this and this in which they have used the same promoter and have given the primer sequence to isolate it. But neither any reference has been given on the source of this primer sequence nor the promoter sequence itself been reported. Since I want to clone the promoter (from different strain), I wish to know its sequence (and size) so that I can choose appropriate restriction enzymes for cloning.
Lactobacillus acidophillus genome is already known and is available at here and here
How can I go about finding out the LDH promoter sequences so that I can design the primers with appropriate RE site and go ahead with cloning?
