Small nucleolar RNA R160 of the members of the box C/D family function in directing site-specific 2'-O-methylation of substrate RNAs. snoR160 was identified by computational screening of the rice "Oryza sativa" and is predicted to acts as a methylation guide for 25S ribosomal RNA in plants. snoR160 has also been alternatively named snoZ270 in rice. Small nucleolar RNA R160 Samm nucleolar RNA R160 (also known as snoR160) is a non-coding RNA (ncRNA) molecule identified in plants which functions in the modification of other small nuclear RNAs (snRNAs). This type of modifying RNA is usually located in the nucleolus of the eukaryotic cell which is
12-oxophytodienoate reductase 12-oxophytodienoate reductase 12-oxophytodienoate reductase (OPRs) is an enzyme of the family of Old Yellow Enzymes (OYE). OPRs are grouped into two groups: OPRI and OPRII – the second group is the focus of this article, as the function of the first group is unknown, but is the subject of current research. The OPR enzyme utilizes the cofactor flavin mononucleotide (FMN) and catalyzes the following reaction in the jasmonic acid synthesis pathway: This reaction occurs in peroxisomes in plants. Several isozymes have been discovered, with varying substrate stereospecificity: three in "Lycopersicon esculentum", 13 in "Oryza sativa", and five in "Arabidopsis thaliana".
