Gene PA1377 from Pseudomonas aeruginosa encodes a 177-amino-acid conserved hypothetical protein of unknown function. The structure of this protein (termed pitax) has been solved in space group I222 to 2.25 A resolution. Pitax belongs to the GCN5-related N-acetyltransferase family and contains all four sequence motifs conserved among family members. The beta-strand structure in one of these motifs (motif A) is disrupted, which is believed to affect binding of the substrate that accepts the acetyl group from acetyl-CoA.
来自铜绿假单胞菌的PA1377基因编码一种功能未知的由177个氨基酸组成的保守假设蛋白。该蛋白（称为pitax）的结构已在空间群I222中解析，分辨率达到2.25埃。Pitax属于与GCN5相关的N - 乙酰转移酶家族，并且包含家族成员中保守的所有四个序列基序。这些基序之一（基序A）中的β链结构被破坏，据信这会影响从乙酰辅酶A接受乙酰基的底物的结合。
