Domain organization of Nitric Oxide Synthases (NOSs). See text and Table 1 for details and accession numbers. A. Chordate NOS domain organization. Three distinct types are observed neuronal, inducible and endothelial in chordates. Interestingly, only neuronal like NOSs have PDZ domain in their N-terminal. Note: the length of NOSs in the schematic illustrations correspond to the size of the NOS proteins. All domains were analyzed using SMART (a Simple Modular Architecture Research Tool) database (469) http://smart.embl-heidelberg.de/. B. Invertebrate NOS domain organization (see the next page).
