kynurenine + pyruvate => 4-(2-aminophenyl)-2,4-dioxobutanoic acid + alanine [CCBL2]

CCBL2 (KAT 3) catalyzes the reaction of kynurenine and pyruvate to form 4-(2-aminophenyl)-2,4-dioxobutanoate and alanine. CCBL2 is known only as the predicted protein product of a cloned human gene closely homologous to CCBL1 (Yu et al. 2006) and all of the structural and catalytic properties annotated here are inferred from those of CCBL1.

CCBL2（KAT 3）催化犬尿氨酸与丙酮酸的反应，生成4-(2-氨基苯基)-2,4-二氧丁酸和丙氨酸。CCBL2仅作为克隆的人源基因的预测蛋白质产物而为人所知，该基因与CCBL1（Yu et al. 2006）高度同源，此处所注明的所有结构和催化性质均从CCBL1推断而来。
