MF

cysteine synthase activity

Catalysis of the reaction: O3-acetyl-L-serine + hydrogen sulfide = L-cysteine + acetate.

GO:0005515

MF

protein binding

Interacting selectively and non-covalently with any protein or protein complex (a complex of two or more proteins that may include other nonprotein molecules).

GO:0005524

MF

ATP binding

Interacting selectively and non-covalently with ATP, adenosine 5'-triphosphate, a universally important coenzyme and enzyme regulator.

GO:0005739

CC

mitochondrion

A semiautonomous, self replicating organelle that occurs in varying numbers, shapes, and sizes in the cytoplasm of virtually all eukaryotic cells. It is notably the site of tissue respiration.

GO:0006535

BP

cysteine biosynthetic process from serine

The chemical reactions and pathways resulting in the formation of cysteine from other compounds, including serine.

GO:0008270

MF

zinc ion binding

Interacting selectively and non-covalently with zinc (Zn) ions.

GO:0009507

CC

chloroplast

A chlorophyll-containing plastid with thylakoids organized into grana and frets, or stroma thylakoids, and embedded in a stroma.

GO:0009567

BP

double fertilization forming a zygote and endosperm

Fertilization where one of the two sperm nuclei from the pollen tube fuses with the egg nucleus to form a 2n zygote, and the other fuses with the two polar nuclei to form the 3n primary endosperm nucleus and then develops into the endosperm. The ploidy le

CC

chloroplast stroma

The space enclosed by the double membrane of a chloroplast but excluding the thylakoid space. It contains DNA, ribosomes and some temporary products of photosynthesis.

GO:0009860

BP

pollen tube growth

Growth of pollen via tip extension of the intine wall.

GO:0016740

MF

transferase activity

Catalysis of the transfer of a group, e.g. a methyl group, glycosyl group, acyl group, phosphorus-containing, or other groups, from one compound (generally regarded as the donor) to another compound (generally regarded as the acceptor). Transferase is the

BP

cysteine biosynthetic process

The chemical reactions and pathways resulting in the formation of cysteine, 2-amino-3-mercaptopropanoic acid.

GO:0030170

MF

pyridoxal phosphate binding

Interacting selectively and non-covalently with pyridoxal 5' phosphate, 3-hydroxy-5-(hydroxymethyl)-2-methyl4-pyridine carboxaldehyde 5' phosphate, the biologically active form of vitamin B6.

MF

identical protein binding

Interacting selectively and non-covalently with an identical protein or proteins.

GO:0048868

BP

pollen tube development

The process whose specific outcome is the progression of a pollen tube over time, from its initial formation to a mature structure.
