Vilnius Lithuania iGEM 2023 team's goal was to create a universal synthetic biology system in ''Komagataeibacter xylinus'' for ''in vivo'' bacterial cellulose polymer composition modification. Firstly, we chose to produce a cellulose-chitin polymer that would later be deacetylated, creating bacterial cellulose-chitosan. This polymer is an easily modifiable platform when compared to bacterial cellulose. The enhanced chemical reactivity of bacterial cellulose-chitosan polymer allows for specific functionalizations in the biomedicine field, such as scaffold design.

Bacterial cellulose-chitin polymer was achieved by increasing the production of UDP-N-acetylglucosamine, which can be recognized as a viable substrate for cellulose synthase and incorporated in the bacterial cellulose polymer. We employed two strategies to produce this material. The first approach was to add N-acetylglucosamine into the growth medium [https://parts.igem.org/Part:BBa_K4719013 BBa_K4719013], and the second one was the production of N-acetylglucosamine by ''K. xylinus'' from simple sugars such as glucose, fructose, and saccharose in the growth medium [https://parts.igem.org/Part:BBa_K4719014 BBa_K4719014].

AGM1

Introduction

Vilnius-Lithuania iGEM 2023 team's goal was to create synthetic biology tools for in vivo alterations of Komagataeibacter xylinus bacterial cellulose polymer composition. Firstly, we chose to produce a cellulose-chitin copolymer that would later be deacetylated, creating bacterial cellulose-chitosan. This polymer is an easily modifiable platform when compared to bacterial cellulose. The enhanced chemical reactivity of the bacterial cellulose-chitosan polymer allows for specific functionalizations in the biomedicine field, such as scaffold design. As a second approach, we designed indigo-dyed cellulose that could be used as a green chemistry way to apply cellulose in the textile industry. Lastly, we have achieved a of bacterial cellulose and polyhydroxybutyrate (PHB) composite, which is synthesized by K. xylinus.

Bacterial cellulose-chitin polymer was achieved by increasing the production of UDP-N-acetylglucosamine, which can be recognized as a viable substrate for cellulose synthase and incorporated in the bacterial cellulose polymer. We employed two strategies to produce this material. The first approach was to add N-acetylglucosamine into the growth medium BBa_K4719013, and the second one was the production of N-acetylglucosamine by K. xylinus from other sugars such as glucose, fructose, and saccharose in the growth medium BBa_K4719014.


Usage and Biology

AGM1 is phosphoacetl-glucosamine mutase. The protein sequence is from Candida albicans. This protein catalyzes the conversion of GlcNAc-6-P into GlcNAc-1-P during the synthesis of uridine diphosphate/UDP-GlcNAc, which is a biosynthetic precursor of chitin and also supplies the amino sugars for N-linked oligosaccharides of glycoproteins (1). This part is used in BBa_K4719013and BBa_K4719014.
