Leucine aminopeptidase (LAP) from bovine lens is the best characterized aminopeptidase and the only LAP for which the amino acid sequence was determined by protein sequencing. Using this sequence information, we isolated a bovine kidney LAP cDNA and compared its deduced amino acid sequence to the published amino acid sequence for bovine lens LAP. Overall, the sequences are highly conserved. However, several differences are observed. The kidney LAP cDNA indicates a 26 amino acid extension at the amino terminus which is not found in the mature purified lens LAP. The cDNA also indicates an additional octapeptide in the C-terminal region which was not indicated in the published lens LAP amino acid sequence but which was required for best fit of crystallographic data regarding bovine lens LAP. Several other single amino acid changes were also noted. Levels of LAP transcripts were examined in bovine lens and kidney tissue as well as in cultured lens cells. Lens epithelial tissue showed only one LAP transcript (2.4 kb) whereas two transcripts (2.0 and 2.4 kb) were observed in cultured lens cells derived from epithelial tissue and in kidney tissue. Using Northern blot analysis, we correlated LAP mRNA levels with previously determined changes of LAP activity in aging lens tissue and in progressively passaged lens epithelial cells which were used to simulate aging in vitro. No differences were found in LAP mRNA levels in epithelial tissue from old and young lenses.(ABSTRACT TRUNCATED AT 250 WORDS)"xsd:string |
