There is a species of yeast cell called Saccharomyces cerevisiae that is commonly known as Baker’s Yeast.
In the lab I am working with Saccharomyces cerevisiae has been genetically engineered to express the ALS5 gene from another yeast called Candida albicans.
Candida albicans is a fungus that causes yeast infections that infect 10 out 1000 people a year. It also kills hundreds of AIDS victims and cancer victims a year. It only attacks people with suppressed immune systems which means it is an opportunistic pathogen.
Candida albicans expresses 6,000 genes one of them is ALS5. ALS genes encode an adhesion glycoprotein. There are 8 different ALS genes: ALS1-ALS7 and ALS9.
