Global Profiling of N-Glycoproteins and N-Glycans in the Diatom Phaeodactylum tricornutum.
Xie X, Du H, Chen J, Aslam M, Wang W, Chen W, Li P, Du H, Liu X. Xie X, et al. Front Plant Sci. 2021 Dec 3;12:779307. doi: 10.3389/fpls.2021.779307. eCollection 2021. Front Plant Sci. 2021. PMID: 34925422 Free PMC article.
N-glycosylation is an important posttranslational modification in all eukaryotes, but little is known about the N-glycoproteins and N-glycans in microalgae. Here, N-glycoproteomic and N-glycomic approaches were used to unveil the N-glycop
