    • An objective of the present invention is to provide a transformant altered so as to produce a secondary metabolite in which a benzene ring of the secondary product is modified at the para-position with a functional group containing a nitrogen atom. A transformant according to the present invention is a transformant of an organism producing a secondary metabolite having a benzene ring skeleton without substitution at the para-position with a functional group containing a nitrogen atom, said transformant being transformed by introducing genes involved in a biosynthetic pathway from chorismic acid to p-aminophenylpyruvic acid, including a gene encoding an amino acid sequence (SEQ ID NO: 2) having 4-amino-4-deoxychorismic acid synthase activity, a gene encoding an amino acid sequence (SEQ ID NO: 4) having 4-amino-4-deoxychorismic acid mutase activity and a gene encoding an amino acid sequence (SEQ ID NO: 6) having 4-amino-4-deoxyprephenic acid dehydrogenase activity, so as to produce a secondary metabolite having a benzene ring skeleton substituted at the para-position with a functional group containing a nitrogen atom. Another objective of the present invention is to provide a novel gene involved in the biosynthetic pathway from chorismic acid to p-aminophenylpyruvic acid. A novel gene according to the present invention comprises genes encoding the amino acid sequences of SEQ ID NOs: 2, 4 and 6 or modified sequences thereof.

    • A moving image encoding apparatus includes a first-step encoding section for executing a plurality of times first-step encoding by use of different quantization control variables; a code-amount estimation section for estimating, for all the quantization control variables, an amount of codes generated for each frame by making use of a plurality of results of the encoding; a code-amount allocation section for allocating an amount of codes for each frame on the basis of results of the estimation; and a second-step encoding section for executing second-step encoding on the basis of the amount of codes allocated to each frame. The first-step encoding section changes the number of times of execution of the encoding in accordance with the attribute of each frame, and omits a portion of processes contained in the coding process in the second and subsequent executions of the encoding process.
