Fig. 1: Summary of organization and function of HxnR-regulon composed of three gene clusters in A. nidulans11.
From: A complete nicotinate degradation pathway in the microbial eukaryote Aspergillus nidulans
Arrows indicate specific hxn genes and relative gene orientation. Lines below the genes indicate gene clusters. Names of clusters are indicated below the lines. Above the arrows, reported roles of genes (hxnS and hxnR10) or roles deduced from domain functions (hxnN,M,T,P,Y,Z,X,W,V11) are indicated. Black arrows indicate enzyme gene products, striped arrows indicate transporter gene products, and the white arrow denotes the pathway-specific transcription factor.
