'''Crystal Structure of phosphatidylinositol mannosyltransferase (PimA) from Mycobacterium smegmatis in complex with GDP'''
+
== Function ==
-
 
+
[https://www.uniprot.org/uniprot/PIMA_MYCS2 PIMA_MYCS2] Catalyzes the addition of a mannose residue from GDP-D-mannose to the position 2 of a phosphatidyl-myo-inositol (PI) to generate a phosphatidyl-myo-inositol bearing an alpha-1,2-linked mannose residue (PIM1). Contrary to PimB, the mannosyltransferase PimA is unable to transfer a mannose residue to the position 6 of the phosphatidyl-myo-inositola of PIM1.<ref>PMID:12068013</ref> <ref>PMID:19638342</ref>

[[Image:Consurf_key_small.gif|200px|right]]
-
Phosphatidylinositol mannosyltransferase (PimA) is an essential enzyme for mycobacterial growth that catalyses the first mannosylation step in phosphatidyl-myo-inositol mannoside (PIM) biosynthesis. The enzyme belongs to the large GT4 family of glycosyltransferases, for which no structure is currently available. Recombinant purified PimA from Mycobacterium smegmatis has been crystallized in the presence of GDP and myo-inositol. The crystals belong to space group P2(1)2(1)2(1), with unit-cell parameters a = 37.2, b = 72.4, c = 138.2 A, and diffract to 2.4 A resolution.
