Despite lacking the secretory signal sequence, this cytosolic enzyme has been found localized at the surface of several bacteria and fungi. As a surface protein, GAPDH exhibits various adhesive functions, thereby facilitating colonization and invasion of host tissues.<jats:italic>Streptococcus agalactiae<\/jats:italic>, also known as group B streptococcus (GBS), binds onto the host using its surface adhesins and causes sepsis and pneumonia in neonates. GAPDH is one of the surface adhesins of GBS binding to human plasminogen and is a virulent factor associated with host colonization. Although the surface-associated GAPDH has been shown to bind to a variety of host extracellular matrix (ECM) molecules in various bacteria, the molecular mechanism underlying their interaction is not fully understood. To investigate this, structural studies on GAPDH of<jats:italic>S. agalactiae<\/jats:italic>were initiated. The<jats:italic>gapC<\/jats:italic>gene of<jats:italic>S. agalactiae<\/jats:italic>NEM316 encoding GAPDH protein was cloned into pET-28a vector, overexpressed in<jats:italic>Escherichia coli<\/jats:italic>BL21(DE3) cells and purified to homogeneity. The purified protein was crystallized using the hanging-drop vapour-diffusion method. The GAPDH crystals obtained in two different crystallization conditions diffracted to 2.8 and 2.6\u2005\u00c5 resolution, belonging to two different space groups<jats:italic>P<\/jats:italic>2<jats:sub>1<\/jats:sub>and<jats:italic>P<\/jats:italic>2<jats:sub>1<\/jats:sub>2<jats:sub>1<\/jats:sub>2<jats:sub>1<\/jats:sub>, respectively. The structure was solved by molecular replacement and structure refinement is now in progress.<\/jats:p>","DOI":"10.1107\/s2053230x14011418","type":"journal-article","created":{"date-parts":[[2014,6,17]],"date-time":"2014-06-17T17:03:40Z","timestamp":1403024620000},"page":"938-941","update-policy":"https:\/\/doi.org\/10.1107\/cm_01","source":"Crossref","is-referenced-by-count":5,"title":["Cloning, expression, purification, crystallization and preliminary X-ray diffraction analysis of glyceraldehyde-3-phosphate dehydrogenase from<i>Streptococcus agalactiae<\/i>NEM316"],"prefix":"10.1107","volume":"70","author":[{"given":"Revathi","family":"Nagarajan","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Karthe","family":"Ponnuraj","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"329","published-online":{"date-parts":[[2014,6,18]]},"reference":[{"key":"us5057_bb1","doi-asserted-by":"crossref","first-page":"244","DOI":"10.1007\/s15010-003-3182-6","volume":"31","author":"Arisoy","year":"2003","journal-title":"Infection"},{"key":"us5057_bb2","doi-asserted-by":"crossref","first-page":"271","DOI":"10.1107\/S0907444910048675","volume":"67","author":"Battye","year":"2011","journal-title":"Acta Cryst.
