  Identification of rice Os4BGlu13 as a β-glucosidase which hydrolyzes gibberellin A4 1-O-β-d-glucosyl ester, in addition to tuberonic acid glucoside and salicylic acid derivative glucosides

  摘要：

  Gibberellin 1-O-beta-D-glucose ester hydrolysis activity has been detected in rice seedling extracts, but no enzyme responsible for this activity has ever been purified and identified. Therefore, gibberellin A4 glucosyl ester (GA(4)-GE) beta-D-glucosidase activity was purified from ten-day rice seedling stems and leaves. The family 1 glycoside hydrolase Os4BGlu13 was identified in the final purification fraction. The Os4BGlu13 cDNA was amplified from rice seedlings and expressed as an N-terminal thioredoxin-tagged fusion protein in Escherichia coll. The purified recombinant Os4BGlu13 protein (rOs4BGlu13) had an optimum pH of 4.5, for hydrolysis of p-nitrophenyl beta-D-glucopyranoside (pNPGlc), which was the best substrate identified, with a k(cat)/K-m of 637 mM(-1) s(-1). rOs4BGlu13 hydrolyzed helicin best among natural glycosides tested (K-cat/K-m, of 74.4 mM(-1) s(-1)). Os4BGlu13 was previously designated tuberonic acid glucoside (TAG) beta-glucosidase (TAGG), and here the k(cat)/K-m of rOsBGlu13 for TAG was 6.68 mM(-1) s(-1), while that for GA4-GE was 3.63 mM(-1) s(-1) and for salicylic acid glucoside (SAG) is 0.88 mM(-1) s(-1). rOs4BGlu13 also hydrolyzed oligosaccharides, with preference for short beta-(1 -> 3)-linked over beta-(1 -> 4)linked glucooligosaccharides. The enzymatic data suggests that Os4BGlu13 may contribute to TAG, SAG, oligosaccharide and GA4-GE hydrolysis in the rice plant, although helicin or a similar compound may be its primary target.

  Synthesis and Bioactivity of Potassium β-D-Glucopyranosyl 12-Hydroxy Jasmonate and Related Compounds

  摘要：

  Albizzia saman是一种豆科植物，它在白天气息张开的叶子，夜间则将叶子折叠休息。β-d-葡萄糖吡喃苷12-羟基茉莉酸酯（1）被鉴定为控制这种叶子运动的内源性化学因子。我们开发了一种简洁的合成方法，通过9个步骤从（+）-2合成光学上纯净的（−）-1，总产率为58%。同样，作为结构-活性关系（SAR）研究的类物质1的类似物，如epi-LCF（13）、对映体（14）和半乳糖苷（19）也被合成。SAR研究的结果强烈表明，1的闭叶活性的机制与甲基茉莉酸酯的机制不同，并且还表明涉及了一种不同类型的靶蛋白，该蛋白识别茉莉酸衍生物的反式异构体。

• Two Jasmonoid Glucosides and a Phenylvaleric Acid Glucoside from<i>Perilla frutescens</i>
  作者：Tomoyuki Fujita、Kenji Terato、Mitsuru Nakayama

  DOI：10.1271/bbb.60.732

  日期：1996.1

  Three new glucosidic constituents (1–3) were isolated from the methanolie extract of Perilla frutescens. Two of these compounds (t and 2) were jasmonoid glucosides and were determined to be 5’-β-D-glueopyranosyloxyjasmonic acid and 3-β-D-glucopyranosyl-3-epi-2-isocucurbic acid, respectively. The other one (3) was a new glucoside of phenylvaleric acid that was elucidated to be 3-β-D-glucopyranosyloxy-5-phenylvaleric acid. Its aglycone was also found for the first time in nature.

  Four new phenolic glycosides, (27hydroxy-3-methoxy-5-allyl)phenyl beta-D-(6-O-E-sinapoyl)glucopyranoside (1), (1'R,5'R)-5-(5-carboxymethyl-2-oxocyclopentyl)-3Z-pentenyl beta-D-(6-O-galloyl)glucopyranoside (2), (S)-alpha-terpinyl [alpha-L-(2-O-galloyl)arabinofuranosyl]-(1 -> 6)-beta-D-glucopyranoside (3), and (R)-alpha-terpinyl [alpha-L-(2-O-galloyl)arabinofuranosyl]-(1 -> 6)-beta-D-glucopyranoside (4), were isolated from the berries of Pimenta dioica together with eight known flavonoids. The structures of 1-4 were elucidated on the basis of MS and NMR data and enzymatic hydrolysis. All four glycosides showed radical - scavenging activity against 1,1-diphenyl-2-picrylhydrazyl (DPPH) radicals.
