Extrachromosomal elements were found in a strain of X. dendrorhous, and were characterized as linear DNA forming two well defined groups, pPh1 with 3 high-copy-number molecules, pPh11 (6.9 kb), pPh12 (5.7), pPh13 (4.7), and pPh2 with 2 low-copy-number molecules, pPh21 (3.6 kb), pPh22 (3.0). A 4077 bp fragment from pPh13 was cloned in pUC18 (pDK1) and sequenced (accession no. AJ 278,424). Seven putative ORF and some possible regulator sequences were defined.
在一株红法夫酵母中发现了染色体外元件,其特征为线性DNA,形成两个明确的组,pPh1有3个高拷贝数分子,即pPh11(6.9 kb)、pPh12(5.7 kb)、pPh13(4.7 kb),pPh2有2个低拷贝数分子,即pPh21(3.6 kb)、pPh22(3.0 kb)。来自pPh13的一个4077 bp片段克隆于pUC18(pDK1)并测序(登录号AJ 278424)。确定了7个推定的开放阅读框和一些可能的调控序列。
