Pahawh Hmong (RPA: Phaj hauj Hmoob [pʰâ hâu m̥ɔ̃́], Pahawh: 𖬖𖬰𖬝𖬵 𖬄𖬶𖬟 𖬌𖬣𖬵 [pʰâ hâu m̥ɔ̃́]; known also as Ntawv Pahawh, Ntawv Keeb, Ntawv Caub Fab, Ntawv Soob Lwj) is an indigenous semi-syllabic script, invented in 1959 by Shong Lue Yang, to write two Hmong languages, Hmong Daw (Hmoob Dawb / White Miao ...

2016年4月7日 · In this study, the functions of five putative (R)-specific enoyl-CoA hydratases (R-ECHs) in Haloferax mediterranei, named PhaJ1 to PhaJ5, respectively, were thoroughly investigated.

PhaJ4 是 PHA 合成的主要单体供应商，以 FA 作为唯一的碳源和能源，优先选择 C8 和 C10 底物，而 PhaJ1 显示优先选择 C6 底物。然而，当所有三个 PhaJ 同源物都被删除时，突变体仍然积累了高达细胞干重 (CDW) 的 10.7% 的 PHA。删除 ( R)-3-hydroxydecanoyl-ACP:CoA trans

2003年1月15日 · The use of (R)-specific enoyl-coenzyme A (CoA) hydratase (PhaJ) provides a powerful tool for polyhydroxyalkanoate (PHA) synthesis from fatty acids or plant oils in recombinant bacteria. PhaJ provides monomer units for PHA synthesis from the fatty acid ß …

2020年9月1日 · Capability of strain CYR1 to utilize various fatty acids (SCFA and MCFA), and its subsequent conversion in to biopolymers like PHA was evaluated. Further, PHA production pathway was postulated by identifying the four genes i.e., phaA, phaB, phaC, phaJ, which are responsible for encoding the four important enzymes involved in PHA synthesis ...

2023年2月10日 · (R)-Specific enoyl-coenzyme A hydratase (PhaJ) was considered to be the main supplier of monomers for PHA synthesis by converting the β-oxidation intermediate, trans-2-enoyl-CoA to (R)-3-hydroxyacyl-CoA when fatty acids (FA) are used.

2003年1月15日 · The use of (R)-specific enoyl-coenzyme A (CoA) hydratase (PhaJ) provides a powerful tool for polyhydroxyalkanoate (PHA) synthesis from fatty acids or plant oils in recombinant bacteria. PhaJ provides monomer units for PHA synthesis from the fatty acid ß …

PHAs are composed of hydroxy fatty acids and represent a complex class of intracellular storage polymers synthesized by various bacteria and archaea. PHAs are produced in the presence of excess carbon source while growth is inhibited due to limited nutrient availability. PHAs are deposited as water-insoluble granules inside the cells (Figure 1).

2024年1月14日 · Bacterial polyhydroxyalkanoates (PHAs) are bio-based polymeric materials that show high biodegradability not only in soil but also in the marine environments, and produced from renewable resources; making them promising materials that contribute to achieving Sustainable Development Goals (SDGs).

(R)-Specific enoyl-coenzyme A hydratase (PhaJ) was considered to be the main supplier of monomers for PHA synthesis by converting the β-oxidation intermediate, trans-2-enoyl-CoA to (R)-3-hydroxyacyl-CoA when fatty acids (FA) are used. Three PhaJ homologues, PhaJ1, PhaJ4 and MaoC, are annotated in P. putida KT2440.
