Two orthorhombic crystal forms (P2(1)2(1)2, a = 30.5 A, b = 44.5 A, c = 40.5 A; I2(1)2(1)2(1) (or I222), a = 30.1 A, b = 66.5 A, c = 35.5 A) of human neutrophil cationic peptide 1 have been characterized. The P2(1)2(1)2 form contains two peptides (Mr = 3425) per asymmetric unit; the I2(1)2(1)2(1) form contains one peptide per asymmetric unit. Both crystal forms diffract to beyond 1.8 A resolution.
已对人中性粒细胞阳离子肽1的两种正交晶型（P2(1)2(1)2，a = 30.5 Å，b = 44.5 Å，c = 40.5 Å；I2(1)2(1)2(1)（或I222），a = 30.1 Å，b = 66.5 Å，c = 35.5 Å）进行了表征。P2(1)2(1)2晶型每个不对称单元包含两个肽（Mr = 3425）；I2(1)2(1)2(1)晶型每个不对称单元包含一个肽。两种晶型的衍射分辨率均超过1.8 Å。
