Fig. 3From: Construction of a tunable promoter library to optimize gene expression in Methylomonas sp. DH-1, a methanotroph, and its application to cadaverine productionMetabolic pathways of Methylomonas sp. DH-1 for the production of cadaverine from methane. Reactions mediated by heterologous enzymes are shown in red. CadA, l-lysine decarboxylase; CadB, lysine/cadaverine antiporter proteinBack to article page
