Total numbers of green and red genes recovered by Moustafa et al. (81) that encode functional protein classes well conserved in C. merolae

Functional classa	Pt/Tpj
	Green	Red
Ribosome associatedb	13/15	10/14
tRNA associatedc	7/4	14/12
DNA replicationd	5/3	3/3
Nuclear structurale	5/8	1/0
Endomembrane traffickingf	9/5	0/1
Protein foldingg	22/22	11/11
Protein degradationh	18/28	12/14
Amino acid metabolismi	20/18	4/13

^aFunctional classes likely to be relatively unreduced in the C. merolae genome were identified from reference 78; gene numbers were quantified by keyword searches across the red and green data sets in reference 81.

^bRibosome structural/ribosome binding.

^cPrincipally aminoacyl-tRNA synthetase/ligase.

^dDNA nuclease/polymerase/ligase/gyrase/topoisomerase.

^eHistone/chromosome/centromere/nucleosome structural proteins. Excludes histone-modifying and chromatin-remodeling enzymes.

^fSNARE/coatomer/sec/rab proteins. Includes biosynthesis proteins.

^gHsp/bip/calreticulin/calnexin/ERp24/ERp57/protein and peptidyl isomerase/other chaperone/chaperonin.

^hPeptidase/protease/proteinase. Includes inhibitors.

ⁱAll amino acid related (e.g., alanine/alanyl related), with the exception of chaperones, peptidases, tRNA ligases, sugar and prenyltransferases, and amino acid-specific protein kinases and phosphatases.

^jPt, genes identified in P. tricornutum; Tp, genes identified in T. pseudonana.
