Autor: Hao Cheng, Guo-Xiong Liu, Fei Wang, Ke Wang, Li-Tao Ruan, Lin Yang

Publikováno v: Asian Journal of Andrology, Vol 24, Iss 6, Pp 628-632 (2022)

We wanted to determine whether shear wave elastography (SWE) could be used to evaluate the aging degree of the corpus cavernosum (CC) and to identify the histological basis of changes in SWE measurements during the aging process. We performed a cross

Mining and characterization of two amidase signature family amidases from Brevibacterium epidermidis ZJB-07021 by an efficient genome mining approach

Autor: Li-Tao Ruan, Ren-Chao Zheng, Yu-Guo Zheng

Publikováno v: Protein Expression and Purification. 126:16-25

Amidases have received increasing attention for their significant potential in the production of valuable carboxylic acids. In this study, two amidases belonging to amidase signature family (BeAmi2 and BeAmi4) were identified and mined from genomic D

A novel amidase from Brevibacterium epidermidis ZJB-07021: gene cloning, refolding and application in butyrylhydroxamic acid synthesis

Autor: Yu-Guo Zheng, Ren-Chao Zheng, Li-Tao Ruan

Publikováno v: Journal of Industrial Microbiology and Biotechnology. 43:1071-1083

A novel amidase gene (bami) was cloned from Brevibacterium epidermidis ZJB-07021 by combination of degenerate PCR and high-efficiency thermal asymmetric interlaced PCR (hiTAIL-PCR). The deduced amino acid sequence showed low identity (≤55 %) with o
