Very rapid rates of gene conversion were observed between duplicated alpha-amylase-coding sequences in Drosophila melanogaster. This gene conversion process was also seen in the related species Drosophila erecta. Specifically, there is virtual sequence identity between the coding regions of the two genes within each species, while the sequence divergence between species is close to that expecte...

Alpha-Amylase from the antarctic psychrophile Altermonas haloplanktis is synthesized at 0 +/- 2 degrees C by the wild strain. This heat-labile alpha-amylase folds correctly when overexpressed in Escherichia coli, providing the culture temperature is sufficiently low to avoid irreversible denaturation. In the described expression system, a compromise between enzyme stability and E. coli growth r...
