3.1.1.49 | evolution |
BnSCE3 is classifed as a member of the SGNH hydrolase subfamily of GDSL-lipases which cleave ester bonds in a wide array of lipids. Sinapine esterase BnSCE3 kept the catalytic mechanism of the hydrolytic ancestor but experienced a change in substrate specificity |

sinapine esterase is classifed as a member of the SGNH hydrolase subfamily of GDSL-lipases which cleave ester bonds in a wide array of lipids |

3.1.1.49 | metabolism |
1-O-sinapoylglucose, produced by UDP-glucose:sinapate glucosyltransferase during seed development, is converted to sinapine by sinapoylglucose:choline sinapoyltransferase and hydrolyzed by sinapoylcholine (sinapine) esterase in germinating seeds. The released sinapate feeds via sinapoylglucose into the biosynthesis of sinapoylmalate in the seedlings catalyzed by sinapoylglucose:L-malate sinapoyltransferase. Pathway of sinapate ester biosynthesis, overview |

3.1.1.49 | metabolism |
a portion of choline enters the phospholipid metabolism, and sinapate is routed via 1-O-sinapoyl-beta-D-glucose into sinapoylmalate |

3.1.1.49 | physiological function |
during early stages of seedling development, a sinapine esterase BnSCE3 hydrolyzes sinapine, releasing choline and sinapate, metabolic changes in developing seedlings of wild-type and enzyme overexpressing plants, overview |

3.1.1.49 | physiological function |
sinapoylmalate is involved in protecting the leaves against the deleterious effects of UV-B radiation. Sinapine might function as storage vehicle for ready supply of choline for phosphatidylcholine biosynthesis in young seedlings |
