    • Novel mammalian phospholipase (PLA2) nucleotide sequences and low molecular weight (about 14 KD) amino acid sequences encoded thereby are disclosed. More particularly, a cloned human HPLA2 cDNA expressing HPLA2-10 and its cloned rat RPLA2 cDNA counterpart, expressing RPLA2-10, which are characterized as PLA2 Type IV, are disclosed. A second type of PLA2 cDNA, characterized as PLA2 Type III and exemplified by a rat PLA2 cDNA encoding RPLA2-8 and a partial human PLA2 nucleotide sequence encoding HPLA2-8, is disclosed. Expression of the cDNAs encode the two new types of PLA2 enzymes which have phospholipase activity. The novel PLA2s do not include disulfide bridges between cysteine amino acids 11 and 77 or elapid loops. However, the novel PLA2s may include amino acid COOH-terminal extensions which can vary in length. Seventeen of the eighteen absolutely conserved amino acids in all active 14 KD PLA2s are believed to be conserved in RPLA2-8 and HPLA2-8, whereas all eighteen are believed to be conserved in RPLA2-10 and HPLA2-10. Because the encoded sequences of RPLA2-8 and HPLA2-8 include only 16 cysteine amino acids, they have been designated as Type III. RPLA2-10 and HPLA2-10 are designated as Type IV since their encoded sequences include only 12 cysteine amino acids.
    • 公开了由此编码的新型哺乳动物磷脂酶(PLA2)核苷酸序列和低分子量(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14 KD 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。
