Description : (gnl|cdd|68872 : 221.0) no description available & (at3g47450 : 102.0) Encodes a protein with similarity to the bacterial YqeH GTPase required for proper ribosome assembly. In Arabidopsis, mutant analyses show that this protein regulates growth and hormonal signaling in plants. It also attenuates oxidative stress and reactive oxygen species (ROS). It also seems to be involved in regulating leaf senescence and cell death. This gene product is also involved in nitric oxide biosynthesis in response to ABA but not exogenous H2O2. This protein also appears to be required for proper plastid biogenesis. Levels of several plastid-localized proteins, including RBCL, ClpP1, and the MEP biosynthesis enzymes DXS and DXR are altered in rif1-1 mutants. This protein was originally characterized as a mitrochondrial-localized nitric oxide synthase, but, the synthase activity was later disproven. In addition, new studies with GFP fusion proteins and chloroplast import assays suggest that this protein is found in chloroplasts.; NO ASSOCIATED 1 (NOA1); FUNCTIONS IN: GTPase activity; INVOLVED IN: in 8 processes; LOCATED IN: mitochondrion, chloroplast; EXPRESSED IN: 21 plant structures; EXPRESSED DURING: 13 growth stages; BEST Arabidopsis thaliana protein match is: P-loop containing nucleoside triphosphate hydrolases superfamily protein (TAIR:AT3G57180.1); Has 1589 Blast hits to 1531 proteins in 754 species: Archae - 6; Bacteria - 1199; Metazoa - 159; Fungi - 35; Plants - 109; Viruses - 0; Other Eukaryotes - 81 (source: NCBI BLink). & (q6ypg5|nos_orysa : 94.0) Putative nitric-oxide synthase (EC 1.14.13.39) - Oryza sativa (Rice) & (gnl|cdd|37260 : 85.5) no description available & (reliability: 204.0) & (original description: no original description)
