Abstract

fetched live from OpenAlex

Acid phosphatases (APases) catalyze the hydrolysis of inorganic phosphate (Pi) from a broad range of Pi-monoesters with an acidic pH optimum. The liberated Pi is reassimilated into cellular metabolism via mitochondrial or chloroplastic ATP synthases of respiration or photosynthesis, respectively. Eukaryotic APases exist as a wide variety of tissue- and/or cellular compartment-specific isozymes that display marked differences in their physical and kinetic properties. Increases in intracellular (vacuolar) and secreted APase activities are useful biochemical markers of plant nutritional Pi deficiency. The protocols for protein extraction, APase activity determination and measurement of soluble protein concentration from plant tissues or cell suspension cultures are presented., 酸性磷酸酶(APase)催化来自具有酸性pH最佳值的宽范围的P 1 - 单酯的无机磷酸盐(P 1)的水解。 释放的Pi分别通过呼吸或光合作用的线粒体或叶绿体ATP合酶再吸收到细胞代谢中。 真核APase作为多种组织和/或细胞区室特异性同工酶存在,其在它们的物理和动力学性质上显示出显着的差异。 细胞内(液泡)和分泌的APase活性的增加是植物营养缺乏的有用的生物化学标记物。 提出了蛋白质提取,APase活性测定和来自植物组织或细胞悬浮培养物的可溶性蛋白质浓度的测定方案。

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
