The phrase "a minor contribution of" is correct and usable in written English.
It can be used when discussing the significance or impact of a contribution in a particular context, often to downplay its importance.
Example: "The study revealed a minor contribution of external factors to the overall results, suggesting that internal variables played a more significant role."
Alternatives: "a small contribution of" or "a negligible contribution of".
Taken together, the differences in yields, g values, and proton hyperfine couplings detected in the EPR spectra of the multiple-Tyr/Trp variants of CcP recorded at both 285 and 9 GHz are consistent with two predominant, and chemically different, Tyr radicals contributing to the wild-type Tyr EPR spectrum of CcP with a minor contribution of a third species, as summarized in Table 1.
