초록
치아 우식은 석회화 조직의 일부가 용해되고 파괴되는 감염성 세균 질환이다. 최근에 보고된 치아우식증 관련 미생물에 대한 연구는 대부분이 Streptococcus mutans와 같은 Mutans streptococci 에 초점을 맞추고 있다. Mutans streptococci 는 7가지의 서로 다른 종( S. cricetus, S. downei, S. ferus, S. macacae, S. mutans, S. rattus, S. sobrinus ) 과 8가지의 혈청형( serotype a-h )을 모두 포함하여 일컫는다. 산 생성으로 인한 치아의 법랑질 탈회뿐 아니라 치면에 접착하여 군집를 형성하는 것이 균의 독성에 있어 중요하다. 그러므로 우식은 치태와 밀접한 관련이 있다. 이런 초기 군집 형성은 antigen I/II(AgI/II) 와 glucosyltransferase(GTF)에 의해 이루어 진다. 그러므로, AgI/II 와 GTF 는 S. mutans GS-5에 대한 백신 개발에 있어 적당한 목표가 된다. 본 실험은 S. mutans GS-5로부터 agI/II 와 gtfD 유전자를 복제하고 나열하였다. 핵산의 나열순서 분석결과 앞서 보고된 나열과 높은 일치도를 보였다. 복제된 AgI/II 와 앞서 보고된 S. mutans GS-5의 해당 부위의 280개의 핵산은 완벽하게 일치하였다. gtfD와 S. mutans UA159와 비교시, 105개의 아미노산 중 4부위에서 변화를 관찰하였다.
Abstract
Streptococci are Gram-positive, facultative anaerobes and have no catalase activities. Among mutans streptococci containing -type hemolytic activity, S. mutans is a causative agent for dental caries. As well as acid production yielding the demineralization of tooth enamel, adherence and colonization of S. mutans to the teeth are also important for its virulence. These early colonization are accomplished by the bacterial fibrillar protein, Antigen I/II (AgI/II), and glucosyltransferase (GTF). Therefore, AgI/II and GTF are reasonable targets for the development of vaccine against S. mutans GS-5. The agI/II and gtfD genes from S. mutans GS-5 were cloned and sequenced. Sequence analyses showed the nucleotides sequence of cloned genes had high homology to the sequences previously reported. The sequence alignment of 280 nucleotides between the cloned AgI/II and the available sequence of the corresponding S. mutans GS-5 showed the perfect match. Comparing with the sequence of gtfD from S. mutans UA159, the corresponding nucleotide sequence of S. mutans GS-5 showed some mismatches and the mismatches introduced changes in four residues out of 105 amino acids, yielding four missense mutations.
