    Abstract: In prokaryotes, the σ(54) promoters are unique regulatory elements and have attracted much attention because they are in charge of the transcription of carbon and nitrogen-related genes and participate in numerous ancillary processes and environmental responses. All findings on σ(54) promoters are favorable for a better understanding of their regulatory mechanisms in gene transcription and an accurate discovery of genes missed by the wet experimental evidences. In order to provide an up-to-date, interactive and extensible database for σ(54) promoter, a free and easy accessed database called Pro54DB (σ(54) promoter database) was built to collect information of σ(54) promoter. In the current version, it has stored 210 experimental-confirmed σ(54) promoters with 297 regulated genes in 43 species manually extracted from 133 publications, which is helpful for researchers in fields of bioinformatics and molecular biology. Pro54DB is freely available on the web at with all major browsers supported. or © The Author 2016. Published by Oxford University Press. All rights reserved. For Permissions, please e-mail:
