Several patterns of enzymology for L-tyrosine biosynthesis exist in modern microorganisms, each differing in the apparent degree of regulatory efficiency. The extent of pathway evolution in a particular organism may reflect the relative selective pressure for regulation encountered in different ecological niches.
现代微生物中存在几种L-酪氨酸生物合成的酶学模式,每种模式在明显的调节效率程度上有所不同。特定生物体中途径进化的程度可能反映了在不同生态位中遇到的调节的相对选择压力。
