Study on the Crystallization Process of Labeled GL-7-ACA Acylase CA130 Complex 7β-bromoacetyl amino cephalosporanic acid (BA-7-ACA), an analog of glutaryl-7-amino cephalosporanic acid (GL-7-ACA), can inhibit and specifically alkylate GL-7-ACA acylase (CA130) from Pseudomonas sp. 130, forming a carbon-carbon bond between BA-7-ACA and the C-2 on indole ring of Trp-β4 residue of CA130.Here we reported that BA-7-ACA labeled CA130 (BA-C130) could self-catalyze the hydrolysis of BA-7-ACA during crystallization process. The hydrolysis was confirmed to be a reaction analogous to the one of GL-7-ACA by comparative MALDI-TOF (matrix-assisted laser desorption/ionization-time of flight) spectrometry analysis.

The study on the phylogenetic relations among these species is very useful for the study on genome and marker-assisted breeding in Brassica species. The karyotypic analysis is one of the most important methods in analysing the phylogenetic relation of species with closer relations. The protocol for inducing high frequency metaphase was established by pretreatment with low temperature and 8hydroxyquinoline, and then the preparation of chromosome and karyotypes analysis of six economical important Brassica species were carried out. According to the karyotypic analysis, it was shown that in the genomes of amphidiploid species, there are genomical components from didiploid species. Our result showed that B. campetris, B. juncea and B. napus belonged to class 2B, while B.

以二倍体B.nigra（B，n=8）基因组为探针，用B.campestris（A，n=10）或B.oleracea（C，n=9）的基因组进行封阻，分别与B.juncea（AB，n=18）和B.carinata（BC，n=17）进行GISH杂交发现，B.juncea和B.carinata基因组中仅有来自于B.nigra的8对染色体表现杂交信号，而其它染色体杂交信号较弱；以B.campestris或B.oleracea基因组为杂交探针与B.napus（AC，n=19）进行GISH杂交发现，所有19对染色体均出现杂交信号，根据杂交结果难以正确判断B.napus基因组中的哪些染色体是来自于A基因组，哪些是来自于C基因组；以rRNA基因（18S-5.8S-26S）为探针的FISH杂交结果表明，B.campestris基因组中rRNA基因位点为6对；B.oleracea为3对；B.nigra为2对；B.carinata为4对；B.juncea为6对；B.napus为6对。
