At the n - terminal end is the variable domain of 26 amino acids in length , which has no conserved mgxxc ( s / q ) xxt sequence essential for n - myristoylation . so it is conferred that the vfcpkl is a soluble protein N端的可變區有26個氨基酸殘基,沒有豆蔻酰化所必需的保守序列mgxxc ( s q ) xxt ,因此推測vfcpk1可能是水溶性蛋白。
The predicted vfcpkl protein with 493 amino acids contains all the structural characteristics of reported cdpks and there are four domains of a variable domain , a kinase domain , an autoinhibitory domain and a calmodulin - like domain from n - to c - terminal end 由編碼區推測的vfcpk1的493個氨基酸序列具有已報道的cdpk的所有典型結構特征,由n端到c端可分為可變區、激酶區、連接區和調節區四個結構域。
Thus , immunologists have sought smaller molecules with the antigen - recognition capability of antibodies . the variable domains of the heavy ( h ) and light ( l ) chains are sufficient for antigen recognition but the non - covalent complex of the two variable domains ( fv ) is unstable . it is possible to genetically engineer a single - chain fv ( scfv ) with the h chain v region connected to the l chain v region via a 15 amino acid linker composed of serine and glycine amino acid residues 二、日本血吸蟲單克隆杭獨特型抗體np30的單鏈狐( scf )的構建、表達及對balbic小鼠誘導保護性作用研究l 、日本血吸蟲單克隆杭獨特型抗體np0的單鏈抗體歸cfv )的構建、表達通過pcr方法體外擴增并經測序驗證的重鏈、輕鏈可變區( vh 、 vl )基因先后重組入原核表達質粒ptha90相應的位點上,中間通過一連接肽( gly在er ) 。
A chirp scaling algorithm for airborne bistatic sar is proposed , which is suitable for the flight configuration that transmitter and receiver follow parallel path with equal velocity in broadside looking mode . airborne bistatic sar echoed signal model of this particular flightpaths is derived . the model is converted into the range doppler space and is mapped from double range variables to single range variable domain 本文建立了這種特殊飛行模式下雙基地sar的回波信號模型,推導了它在距離多普勒域的表達式,解決了信號模型從雙距離變量域向單距離變量域轉化的問題,并推導了cs因子的線性近似表達式,分析了算法中各種近似造成的誤差。
Based on the two - dimensional dct a three - dimensional dct ( discrete cosine transformation ) , which transforms 3d video data from special - temporal field into frequency field is extended . then using fractal we seek a most approximated range block for each variable domain block in frequency field 在二維離散余弦變換的基礎上提出了一種三維離散余弦變換的方法,把三維視頻數據從時空域變換到頻域中,再利用分形來尋找對應每個可變三維頻域值域塊的最佳定義域塊匹配。
