2016 journal article
Comparative Structural and Computational Analysis Supports Eighteen Cellulose Synthases in the Plant Cellulose Synthesis Complex
Scientific Reports, 6(1).
Contributors: B. Nixon *, K. Mansouri n, A. Singh n, J. Du *, n, J. Lee n, E. Slabaugh n, V. Vandavasi*
MeSH headings : Cellulose / biosynthesis; Cellulose / chemistry; Glucosyltransferases / chemistry; Models, Molecular; Plant Proteins / chemistry; Protein Domains; Protein Folding; Protein Structure, Quaternary
TL;DR:
Improved transmission electron microscopy images and image averages of the rosette-type CSC are obtained, revealing the frequent triangularity and average cross-sectional area in the plasma membrane of its individual lobes and multifaceted data support a rosettes CSC with 18 CESAs that mediates the synthesis of a fundamental microfibril composed of 18 glucan chains.

2016 journal article
Prediction of the structures of the plant-specific regions of vascular plant cellulose synthases and correlated functional analysis
Cellulose, 23(1), 145–161.
Contributors: Y. Yingling n , C. Haigler n , A. Singh n, E. Slabaugh n, n & L. Sethaphong n
author keywords: Arabidopsis thaliana; Cellulose synthesis; Computational protein structure prediction; Isoform specificity; Mutant complementation
TL;DR:
Modeling of the mutant P-CR of Atcesa8R362K (fra6) suggested that changes in local structural stability and surface electrostatics may cause the mutant phenotype, and results provide structural clues about the function of plant-specific regions of CESA.

2015 journal article
The valine and lysine residues in the conserved FxVTxK motif are important for the function of phylogenetically distant plant cellulose synthases
Glycobiology, 26(5), 509–519.
author keywords: cellulose synthesis; gametophore formation; phenotypic complementation; root elongation; site-directed mutagenesis
MeSH headings : Amino Acid Motifs; Arabidopsis / enzymology; Arabidopsis / genetics; Arabidopsis Proteins / genetics; Arabidopsis Proteins / metabolism; Bryopsida / enzymology; Bryopsida / genetics; Glucosyltransferases / genetics; Glucosyltransferases / metabolism; Lysine / genetics; Lysine / metabolism; Valine / genetics; Valine / metabolism
TL;DR:
The results support the possibility that the FxVTxK region functions similarly in CESA and BcsA, and show that Physcomitrella provides an efficient model for assessing the effects of engineered CESA mutations affecting primary cell wall synthesis and that diverse testing systems can lead to nuanced insights into CESA structure-function relationships.

2014 journal article
Cellulose synthases: new insights from crystallography and modeling
Trends in Plant Science, 19(2), 99–106.
Contributors: J. Zimmer *, Y. Yingling n , C. Haigler n , n & E. Slabaugh n
MeSH headings : Catalytic Domain; Crystallography; Glucosyltransferases / chemistry; Models, Molecular; Plant Proteins / chemistry
TL;DR:
It is shown how the structures of CelS proteins can be used to generate hypotheses for experiments testing mechanisms of glucan synthesis and translocation in plant CelS, and how these structures impact the understanding of the synthesis of cellulose and other extracellular polysaccharides.
