Carbohydr Polym. 2017 Nov 01;175:178-191. doi: 10.1016/j.carbpol.2017.07.073. Epub 2017 Jul 25.

Silver linden flowers contain different pectins (PSI-PSIII) with immunomodulating properties. PSI is a low-esterified pectic polysaccharide with predominant homogalacturonan region, followed by rhamnogalacturonan I (RGI) with arabinogalactan II and RGII (traces) domains. PSII and PSIII are unusual glucuronidated RGI...

Suppression of PtrDUF579-3 Expression Causes Structural Changes of the Glucuronoxylan in Populus.

Frontiers in plant science

Song D, Gui J, Liu C, Sun J, Li L.
PMID: 27148318
Front Plant Sci. 2016 Apr 11;7:493. doi: 10.3389/fpls.2016.00493. eCollection 2016.

DUF579 (domain unknown function 579) genes have been reported to play diverse roles in cell wall biosynthesis, such as in glucuronoxylan (GX) synthesis. As GX is a major type of hemicelluloses in hard wood species, how DUF579 genes function...

Loos E, Meindl D.
PMID: 24272476
Planta. 1982 Dec;156(3):270-3. doi: 10.1007/BF00393735.

Isolated cell walls of mature Chlorella fusca consisted of about 80% carbohydrate, 7% protein, and 13% unidentified material. Mannose and glucose were present in a ratio of about 2.7:1 and accounted for most of the carbohydrate. Minor components were...

The effects of glucuronic acid and N-acetyl-D-glucosamine on in vitro fertilisation of porcine oocytes.

Reproduction, fertility, and development

Schmidt K, Clark A, Mello A, Durfey C, Buck A, Boyd K, Whitaker BD.

Reprod Fertil Dev. 2015 Jan 14; doi: 10.1071/RD14226. Epub 2015 Jan 14.

High incidences of polyspermic penetration continue to challenge researchers during porcine in vitro fertilisation (IVF). The aim of this study was to reduce the incidence of polyspermy by increasing the perivitelline space thickness with glucuronic acid and N-acetyl-D-glucosamine (GlcNAc)...

Analysis of nucleotide diphosphate sugar dehydrogenases reveals family and group-specific relationships.

FEBS open bio

FEBS Open Bio. 2016 Jan 11;6(1):77-89. doi: 10.1002/2211-5463.12022. eCollection 2016 Jan.

UNLABELLED: UDP-glucose dehydrogenase (UDPGDH), UDP-N-acetyl-mannosamine dehydrogenase (UDPNAMDH) and GDP-mannose dehydrogenase (GDPMDH) belong to a family of NAD (+)-linked 4-electron-transfering oxidoreductases called nucleotide diphosphate sugar dehydrogenases (NDP-SDHs). UDPGDH is an enzyme responsible for converting UDP-d-glucose to UDP-d-glucuronic acid, a product...
