Germin and germin-like proteins (GLPs) belong to the cupin superfamily of proteins, which are functionally most diverse proteins. Germin and GLPs have some unique features as they are highly resistant to proteases and to dissociation by heat, sodium dodecyl sulphate (SDS) and extreme pH. They are water soluble extracellular proteins with enzymatic activities including oxalate oxidase (OxO), superoxide dismutase (SOD) or ADP-glucose pyrophosphate or phosphodiestrase (AGPPase). At the moment seven GLP gene promoter from different organisms have been studied and published. These promoter sequences have been analyzed in this study. It was observed that these promoters have important regulatory elements, which are involved in various important functions. These elements have been compared on the basis of location, copy number and distributed on positive and negative strands. It was also observed that some of these elements are common and remained conserved among all GLP promoters during evolution. These common regulatory elements are related to seed storage proteins, light responsive dehydration and dark-induced senescence and elements specific to expression in pollen. Moreover, it is also found that some of these common elements are responsive to different environmental stresses (salt and pathogen attack) and growth regulators as well. © 2010 Academic Journals.
