The "Raman spectroscopic signature of life" is closely related to haem function in budding yeasts.

Journal of biophotonics - 1 Jan 2011

Chiu Liang-da, Hamaguchi Hiro-o

Abstract excerpt

HEM1 gene encodes δ-aminolevulinate synthase that is required for haem synthesis. It is an essential gene for yeast survival. The Raman spectra of HEM1 knockout (hem1Δ) yeast cells lacks a Raman band at 1602 cm(-1) that has been shown to reflect cell metabolic activity. This result suggests that the molecule giving rise to the"Raman spectroscopic signature of life" is closely related to haem functions in the...
