The activity of intact elongator complex is directed specifically toward the amino - terminal tails of histone h3 and h4 , the predominant acetylation sites are lysine - 14 of histone h3 and lysine - 8 of histone h4 完整的复合物可直接修饰组蛋白h3和h4尾部，其优先乙酰化位点是h3k14和h4k8 。
The purpose of the study was to explore experimental method by means of periodate - lysine - parafoemaldehyde fixative , edta low temperature demineralization and frozen section technique 摘要本研究目的是采用过碘化钠-赖氨酸-多聚甲醛溶液固定， edta低温脱钙、冰冻切片的方法探索一种较理想的实验手段。
( 2 ) l - cystine , tyrosine , dl - aspartic acid , l - lysine were used as soft - templates to regulate and control the crystallization of caco3 . the effects of different amino acid to the growth of caco3 ( 2 )分别以l一肤氨酸、 l一酪氨酸、 dl一天冬氨酸、 l一赖氨酸作为软模板，分别研究了其对碳酸钙晶体生长的影响。
Our selling list includes methionine from degussa , lysine from dacheng , changchun , minerals from lonmon and chuanheng , imported single and complex vitamins , microelements , enzymes , and other medical feed additives 主要经营德国德固赛蛋氨酸、长春大成赖氨酸、四川龙蟒、川恒矿物质、进口单项和复合维生素、微量元素、酶制剂以及各种药物饲料添加剂等。
The substance with antibacteria action obtained from forest frog is made up of alanine , aminoacetic acid , leucine , isoleucine , proline , aminoglutaric acid , threonine , serine , lysine . the substance with antibacteria action is a kind of poly peptide with a micromolecul 纯化的林蛙皮肤抗菌活性物质经尿素? sds ? page电泳分析，表现为一条带，分子量约为6 . 28kda 。
4 . the magnesium ions , l - cystine , tyrosine , dl - aspartic acid , l - lysine , and the mixed system of magnesium ions and amino acid were used as effective soft - templates to regulate and control the crystallization of caccb , respectively 以镁离子、 l -胱氨酸、 l -酪氨酸、 dl -天冬氨酸、 l -赖氨酸以及它们的混合体系为模板，研究了其对碳酸钙晶体生长的调控作用。
This is a very exciting breakthrough , as higher levels of the amino acid lysine improve the overall quality and nutritional value of total protein enormously , and traditional corn varieties are particularly deficient in this essential amino acid 。这是一项十分令人兴奋的技术突破，因为高含量的赖氨酸能显著提高玉米总蛋白的整体质量和营养价值，而传统玉米品种尤其缺乏这种必需氨基酸。
