    • Novel mammalian phospholipase (PLA.sub.2) nucleotide sequences and low molecular weight (about 14KD) amino acid sequences encoded thereby are disclosed. More particularly, a cloned human HPLA.sub.2 cDNA expressing HPLA.sub.2 -10 and its cloned rat RPLA.sub.2 cDNA counterpart, expressing RPLA.sub.2 -10, which are characterized as PLA.sub.2 Type IV, are disclosed. A second type of PLA.sub.2 cDNA, characterized as PLA.sub.2 Type III and exemplified by a rat PLA.sub.2 cDNA encoding RPLA.sub.2 -8 and a partial human PLA.sub.2 nucleotide sequence encoding HPLA.sub.2 -8, is disclosed. Expression of the cDNAs encode the two new types of PLA.sub.2 enzymes which have phospholipase activity. The novel PLA.sub.2 s do not include disulfide bridges between cysteine amino acids 11 and 77 or elapid loops. However, the novel PLA.sub.2 s may include amino acid COOH-terminal extensions which can vary in length. Seventeen of the eighteen absolutely conserved amino acids in all active 14KD PLA.sub.2 s are believed to be conserved in RPLA.sub.2 -8 and HPLA.sub.2 -8, whereas all eighteen are believed to be conserved in RPLA.sub.2 -10 and HPLA.sub.2 -10. Because the encoded sequences of RPLA.sub.2 -8 and HPLA.sub.2 -8 include only 16 cysteine amino acids, they have been designated as Type III. RPLA.sub.2 -10 and HPLA.sub.2 -10 are designated as Type IV since their encoded sequences include only 12 cysteine amino acids.
    • 公开了新型哺乳动物磷脂酶(PLA2)核苷酸序列和由此编码的低分子量(约14KD)氨基酸序列。 更具体地,公开了表达为PLA2 IV型的克隆的表达HPLA2-10的人HPLA2 cDNA及其克隆的大鼠RPLA2 cDNA对应物,表达RPLA2-10。 公开了第二种类型的PLA2,其特征为PLA2型III,并且由编码RPLA2-8的大鼠PLA2 cDNA和编码HPLA2-8的部分人PLA2核苷酸序列示例。 cDNA的表达编码了具有磷脂酶活性的两种新型PLA2酶。 新型PLA2不包括半胱氨酸氨基酸11和77之间的二硫键或elapid环。 然而,新颖的PLA2可以包括可以在长度上变化的氨基酸COOH-末端延伸。 所有活性14KD PLA2中十八个绝对保守氨基酸中的17个被认为在RPLA2-8和HPLA2-8中保守,而所有十八个被认为在RPLA2-10和HPLA2-10中保守。 由于RPLA2-8和HPLA2-8的编码序列仅包含16个半胱氨酸氨基酸,因此已被指定为III型。 RPLA2-10和HPLA2-10被命名为IV型,因为它们的编码序列仅包括12个半胱氨酸氨基酸。
