Does the amino acid sequence in a patent need to be capitalized?

I checked

Intellectual Property Industry Standards of the People's Republic of China - Nucleotide and/or Amino Acid Sequence Listings and Sequence Listing Electronic Document Standards

Original words are as follows

Amino acids should be represented by three-letter symbols consistent with the symbols in Table 3 of Appendix 1, with the first letter capitalized. Amino acid sequences with blanks or internal termination symbols (such as "Ter" or "*" or "·") should not be represented as a single amino acid sequence but should be listed separately as independent amino acid sequences.
