Fusion Proteins

Research reports from W.J. Yao and co-authors provide new insights into fusion proteins

Published in Proteomics Weekly, November 30th, 2009

"We developed a new cell surface display system in Corynebacterium glutamicum based on the C-terminally truncated NCgl1221 anchor protein to increase l-glutamate production from starch directly. The C-terminally truncated NCgl1221 protein is a mutant NCgl1221 and leads to the constitutive export of l-glutamate," researchers in Nanjing, People's Republic of China report.

"The N terminus of alpha-amylase (AmyA) was fused to truncated NCgl1221, and the resulting fusion protein was expressed on the cell surface by IPTG induction. Localization of the fusion protein was confirmed by immunofluorescence microscopy and flow cytometric analysis. The results of l-glutamate...
