ABSTRACT
A chimeric plasmid, pJPuvr4, consists of a 16.7 kbp Haemophilus influenzae Rd chromosomal DNA insert at the EcoRI site of vector pJ1-8. This plasmid complements the UV and gamma ray sensitivity of the mutant strain MBH4. This plasmid carries the wild type allele of gene uvr4 which was localised to a 3.8 kbp DraI fragment, with an internal EcoRI site. Partial sequencing of the gene and its alignment with the published genome sequence of H. influenzae Rd revealed uvr4 to be HI1472. HI1472 is a putatively identified open reading frame (ORF), which has been assigned no function so far. The partial sequence did show nt database match with 3D exon of N cadherin gene of homosepians and moaA gene of H. influenzae. Cadherins are involved in cell adhesion, cell to cell contact and morphogenesis in homosepians and moaA gene codes for molybdenum biosynthesis subunitA. This report implicates HI1472 of Haemophilus influenzae Rd in DNA repair. Nucleotide sequence obtained for the gene uvr4 was compared with the published sequence of gene HI1472. A wild type strain variation was observed at the 592nd nucleotide position corresponding to a change from aspartic acid to threonine.
