[Analysis of POX4 and POX5 gene encoded proteins of Candida tropicalis 1230].

POX4 and POX5 were cloned from Candida tropicalis with a simple method. The sequencing results show differences of POX5 between strain 120 and strain pk233. The searching of these two sequences against the curreent collection of Pfam profile HMMS located regions that belong to known domain families. Secondary structure prediction shows that N-terminal secondary structure of PXP4 and PXP5 are homologous to that of pig liver medium-chain acyl-coA dehydrogenase. Thus, the N-terminal of PXP4 and PXP5 may be involved in FAD binding.
