甘氨酸

Owing to the abroad application of Candida rugosa lipase in the resolution of racemic aminoacides, the prepared lipase was used in the resolution of phenylglycine and tert-leucine. Through the optimization of the reaction conditions, such as reaction substrate, pH, temperature, ion strength and additives, enantiomeric excesses for phenylglycine and tert-leucine reached 96% and 90.1%, respectively, enantiomeric ratio came up to 28. 9 and 15. 4, respectively.

鉴于该酶广泛应用于手性化合物的拆分研究，本论文中选用了两种手性氨基酸作为拆分对象，通过对反应体系中一系列条件的优化，包括底物、pH、温度、离子强度以及添加物的使用，苯甘氨酸和叔亮氨酸的对映体过量值分别达到96%和90.1%，对映催选择率分别达到28.9和15.4。

The effects of FC were abolished by intrathecal administration of kynurenic acid (50 nmol) or 2-amino-5-phosphonovaleric acid (AP-5, 0.5 nmol), but not by 6, 7-dinitroquinoxaline-2, 3-dione (DNQX, 5 nmol), picrotoxin (5 nmol) or strychnine (1 nmol).

，高频刺激前0.5小时鞘内注射特异性NMDA受体拮抗剂AP-5（0.5 nmol）或非选择性谷氨酸受体拮抗剂犬尿酸（50 nmol），FC的效应被阻断；non-NMDA受体拮抗剂DNQX（5 nmol）不能阻断FC的效应；〓（5 nmol）和甘氨酸受体（1 nmol）拮抗剂对FC的效应也无明显影响。

The results showed that the Saccharopolyspora spinosa SP06081 protoplast yield was the highest under these conditions: the collected mycelium from SP06081 grown in Tryptic Soy Broth medium with 0.2% glycin for 48 h was treated by 0.1 mg/mL lysozyme at 28oC for 20 min, then plated on the R2YE medium with sucrose as osmotic stabilizer, the number of regeneration protoplast was up to 108/mL. The protoplast-regenerated strains exhibited changes in morphology and antibiotic production, 29.3% protoplast-regenerated strains was characterized by loose mycelium and abundant broken branches as did their parent. Among them, 58.2% strains presented the trend to positive variation in spinosad yield, with the highest spinosad yield of up to 582.0 mg/L, 85.6% higher than that of their parent.

结果表明：菌体在添加0.2%的甘氨酸的TSB培养基中培养48 h收集， 0.1 mg/mL 溶菌酶， 28oC作用20 min制备原生质体，将原生质体涂布于以蔗糖为渗透压稳定剂的R2YE培养基中，原生质体再生数目最多，达108个/mL以上；原生质体再生菌株在形态和抗生素产量上产生分化， 29.3%的再生菌株形态上保持与亲本菌株一致，具有菌丝松散，断裂分枝多的特点，其中53.2%的再生菌株多杀菌素产量变异向正方向移动，最高产量达到582.0 mg/L，比亲本菌株提高85.6%。

Plant there exists large amount of cell wall egg white in cell wall middle, if structure egg white , zymoprotein etc., structure egg white having mainly expanding egg white , being rich in the glycine proteide and so on studying at present, brings the important effect into play in plant cell wall growth and structural adjustment.
