Tertiary-structure modeling suggests the occurrence of disulfide bonds in the cytosolic form of fructose-bisphosphatase (EC 3.1.3.11) in spinach (Spinacia oleracea L.), sugarbeet (Beta vulgaris L.) and potato (Solanum tuberosum L.). Redox modulation could then control the AMP sensitivity of fructosebisphosphatase in the cytosol, as suggested by the experiments of E. Khayat et al. (1993, Plant Physiol. 101, 57-64). Modeling also reveals two cysteine residues correctly positioned to form a disulfide bond and hence potentially redox-sensitive in the cytosolic glyceraldehyde-3-phosphate dehydrogenase (EC 1.2.1.12) from the facultative crassulacean metabolism plant Mesembryanthemum crystallinum L.
三级结构建模表明,菠菜(Spinacia oleracea L.)、甜菜(Beta vulgaris L.)和马铃薯(Solanum tuberosum L.)中果糖双磷酸酶(EC 3.1.3.11)的胞质形式存在二硫键。正如E. Khayat等人(1993年,《植物生理学》101卷,57 - 64页)的实验所表明的,氧化还原调节可能会控制胞质中果糖双磷酸酶对AMP的敏感性。建模还揭示,在兼性景天酸代谢植物冰花(Mesembryanthemum crystallinum L.)的胞质甘油醛-3-磷酸脱氢酶(EC 1.2.1.12)中,有两个半胱氨酸残基位置正确,可形成二硫键,因此可能对氧化还原敏感。
